STMicroelectronics JAN/JANS/JANSR Diode & Transistor Sourcing | MIL-PRF-19500

Q: Is STMicroelectronics on the MIL-PRF-19500 QPL?

Yes. STMicroelectronics S.A.S. is on the current DLA Land and Maritime QML-19500 list under CAGE Code F8859, with the qualified line at 3, rue de Suisse, CS 60816, F-35208 Rennes Cedex 2, France, and a supporting wafer fab at STMicroelectronics Pte. Ltd., 28 Ang Mo Kio Industrial Park 2, Singapore. STMicroelectronics is one of the only European manufacturers on the QML-19500 list.

Q: Why is STMicroelectronics listed as "S.A.S." on QML-19500?

"S.A.S." stands for Société par actions simplifiée, a French private-company legal form. The DLA QPL entry is against the French operating entity STMicroelectronics S.A.S. because the Rennes, France site is the certified line for MIL-PRF-19500 discrete production, part of ST's broader ESCC and QML-V space and hi-rel supply chain.

Q: What JAN quality levels does STMicroelectronics hold on MIL-PRF-19500?

STMicroelectronics is qualified to JANTXV and JANS on its rad-hard MOSFET lines and to JANS and JANSR on its rad-hard bipolar transistor lines. On top of the standard JANSR wafer-lot high-dose-rate guarantee, ST's JANSR bipolars add a wafer-by-wafer 100 krad(Si) low-dose-rate (0.1 rad/s) test identical to the ESCC 100 krad guarantee — what ST calls JANSR+.

Q: Which MIL-PRF-19500 slash sheets is STMicroelectronics qualified against?

Widely cited ST MIL-PRF-19500 slash sheets include /255 and /291 (small-signal bipolar transistor families), /391 (medium-voltage NPN transistors), /761 and /766 (high-voltage NPN/PNP transistor families), /614 (N-channel rad-hard MOSFET families), /630 (P-channel rad-hard MOSFET families with RHA levels R and F), and /773 (dual complementary NPN+PNP hermetic Flat-8 family). Standard bipolar and rectifier families such as the /477 superfast recovery types also appear in the ST hi-rel catalog.

About STMicroelectronics

STMicroelectronics was formed in June 1987 through the cross-border merger of SGS Microelettronica (the semiconductor arm of Italy's Società Generale Semiconduttori, itself descended from a 1957 SGS-Fairchild joint venture) and Thomson Semiconducteurs (the semiconductor division of France's Thomson-CSF). The combined company traded as SGS-Thomson Microelectronics until Thomson-CSF divested its stake in May 1998, at which point it was renamed STMicroelectronics. Today the ST group is listed on the New York Stock Exchange (NYSE: STM), Euronext Paris (EPA: STMPA) and Borsa Italiana, with group headquarters in Geneva / Plan-les-Ouates, Switzerland and around 50,000 employees worldwide. It is one of Europe's largest semiconductor manufacturers and a strategic supplier to European defense, space, automotive, and industrial programs.

The DLA MIL-PRF-19500 qualification is against the French operating entity STMicroelectronics S.A.S. — the "S.A.S." is the standard French legal form for a private company (Société par actions simplifiée). The certified line is at 3, rue de Suisse, CS 60816, F-35208 Rennes Cedex 2, France, historically the SGS-Thomson center of excellence for space and hi-rel discrete devices. The Rennes site handles final assembly, hermetic sealing, and space-level electrical and radiation test for ST's ESCC, QML-V and JAN portfolios. Wafer manufacturing is performed at STMicroelectronics Pte. Ltd. (Wafer Fab), 28 Ang Mo Kio Industrial Park 2, Singapore, which is listed as the second plant on the QML-19500 entry, with bipolar and RF-power discrete capacity also supported by the ST fab at Tours, France.

ST's hi-rel positioning is unusual because it maintains three parallel qualification systems at the same site: the European Space Components Coordination (ESCC) qualification managed by the European Space Agency (ESA) and CNES; the U.S. QML-V (MIL-PRF-38535) qualification for space-level microcircuits; and the JAN family (MIL-PRF-19500) qualification for discrete semiconductor devices. ST describes this as its "unique triple ESCC, QML, and JAN certification." Very few manufacturers on either side of the Atlantic maintain all three — and in the QML-19500 register specifically, STMicroelectronics stands out as one of the only non-U.S. entries on a list otherwise dominated by American suppliers.

QPL / QML-19500 status

The Defense Logistics Agency (DLA) Land and Maritime real-time list of qualified sources for MIL-PRF-19500 currently shows STMicroelectronics under a single French-entity manufacturer entry with two plant locations:

STMicroelectronics S.A.S. — 3, rue de Suisse, CS 60816, F-35208 Rennes Cedex 2, France (assembly, hermetic seal, test); CAGE Code F8859
STMicroelectronics Pte. Ltd. (Wafer Fab) — 28 Ang Mo Kio Industrial Park 2, Singapore (second listed plant location under the same manufacturer entry)

The same S.A.S. entity, at the same Rennes address, also holds QML-38535 (monolithic microcircuit) certification against Class Q and Class V, with radiation-hardness level 300 K — the U.S. framework under which ST's rad-hard ASICs and ASSPs are qualified. On top of that, the Rennes site is an ESCC-qualified manufacturer against the European Space Agency's parallel component-qualification system, coordinated through the ESCC Chief Inspector at ST and CNES as the ESCC National Contact.

What makes STMicroelectronics distinctive on QPL-19500 is not the number of slash sheets — ST's discrete portfolio is deliberately focused rather than encyclopedic — but the combination of rad-hard qualification with European sovereignty. For a defense or space program that has to satisfy both U.S. DLA requirements and European space-agency (or export-control) requirements from the same authenticated line, ST's Rennes site is one of a very small number of options. For that reason, ST JAN and JANS discrete part numbers often appear on BOMs alongside U.S. QPL-19500 suppliers, either as primary sources for rad-hard bipolars and MOSFETs or as second-source cross-references.

MIL-PRF-19500 quality levels — what JAN, JANTX, JANTXV, JANS and JANSR actually mean

MIL-PRF-19500 is the U.S. Department of Defense performance specification for hermetically-sealed discrete semiconductor devices — diodes, rectifiers, transistors, thyristors, SCRs, and TVS devices — administered by the DLA Land and Maritime office in Columbus, Ohio (the successor organization to DSCC-VQ). The specification defines a stack of ascending product-assurance levels indicated by the prefix on a part number:

Prefix	Level name	What it adds	Typical use case
JAN	Joint Army-Navy	Baseline qualification against slash sheet, Group A/B/C conformance	Ground defense, ruggedized industrial
JANTX	JAN with eXtra Testing	Adds 168-hour burn-in and additional 100% electrical screening	Airborne, avionics, missile
JANTXV	JANTX with Visual inspection	Adds 100% pre-cap internal visual inspection	Higher-reliability avionics, tactical space
JANS	Joint Army-Navy-Space	Adds wafer lot acceptance, Group E conformance and full space screening	Launch vehicles, satellites, deep space
JANSR	JANS + Radiation LAT	Adds wafer-lot radiation lot acceptance testing (RLAT) to a specified RHA level	High-TID orbits, deep space, hardened programs
JANHC / JANKC	Chip / die-level	Unencapsulated die screening for downstream hybrid assembly	MIL-PRF-38534 hybrids, custom modules

For JANTXV, JANS, and JANSR parts, MIL-PRF-19500 further defines up to eleven Radiation Hardness Assurance (RHA) levels, encoded as a single character (E, K, U, M, D, P, L, R, F, G, or H) inserted into the part number just after the quality level prefix. Those characters correspond to Total Ionizing Dose (TID) guarantees ranging from a few krad(Si) at "M" up to 1 Mrad(Si) at "H," and are combined with neutron-fluence guarantees typically on the order of 2 × 10¹² n/cm². STMicroelectronics' rad-hard P-channel MOSFETs on MIL-PRF-19500/630, for example, are qualified at JANTXV and JANS to RHA levels R (100 krad) and F (300 krad).

On top of the DLA JANS/JANSR system, STMicroelectronics adds what it calls a "JANSR+" flow on its rad-hard bipolar transistors: the standard JANSR wafer-lot high-dose-rate (50–300 rad/s per MIL-PRF-19500 Group D, subgroup 2) guarantee is supplemented by an additional wafer-by-wafer 100 krad(Si) low-dose-rate test at 0.1 rad/s, identical to the ESCC 22900 100 krad guarantee. This addresses Enhanced Low Dose Rate Sensitivity (ELDRS) effects that can degrade bipolar devices in the multi-year, low-flux environment of a GEO or deep-space mission and is a differentiator against U.S. JANSR bipolars, which typically only add wafer-lot RLAT at the high dose rate. On top of the older part-by-part Qualified Products List (QPL) model, the DoD now operates a line-level certification called the Qualified Manufacturers List (QML), which is the framework STMicroelectronics S.A.S. is certified against.

STMicroelectronics' MIL-PRF-19500 product portfolio

ST's hermetic discrete portfolio is focused on rad-hard bipolar transistors, radiation-hardened power MOSFETs, and space-grade rectifiers and Schottkys for European and U.S. space and defense programs. The categories below are all supported by current qualifications on the Rennes / Singapore QML-19500 line, generally in parallel with ESCC detailed specifications so the same die can be shipped against either an ESCC or a JAN purchase order. In line with buyer intent, this page lists part families and slash sheets rather than individual JAN part numbers — specific part-number availability is confirmed on quote.

Rad-hard bipolar transistors (JANS and JANSR)

ST's space bipolar portfolio spans NPN and PNP small-signal to high-voltage transistors from 40 V to 600 V, all supported by low-dose-rate (LDR) wafer-by-wafer radiation guarantees at 100 krad(Si). Widely referenced MIL-PRF-19500 slash sheets in the ST catalog include /255 (40 V, 0.8 A NPN small-signal transistors), /291 (−60 V, 0.6 A PNP small-signal transistors), /391 (80 V, 1 A NPN medium-voltage transistors), /761 (160 V, 0.5 A NPN high-voltage transistors), and /766 (high-voltage PNP family, −150 V, 0.5 A PNP high-voltage). Each is offered in both JANS and JANSR screening options. ST also offers hermetic dual complementary NPN + PNP transistors in Flat-8 packages on the /773 slash sheet family (60 V, 0.8 A class), again with JANS and JANSR variants.

Rad-hard N-channel and P-channel MOSFETs

ST's hermetic MOSFET line uses the proprietary STripFET™ process and is qualified under two active MIL-PRF-19500 slash sheets:

MIL-PRF-19500/614 — N-channel enhancement-mode power MOSFET types rad-hard N-channel MOSFET types, JANTXV and JANS, in through-hole and surface-mount packages. Covers total-dose and single-event effects (SEE) with avalanche energy and maximum avalanche current ratings.
MIL-PRF-19500/630 — P-channel enhancement-mode power MOSFET types rad-hard P-channel MOSFET types, JANTXV and JANS, at RHA levels R (100 krad) and F (300 krad).

Both slash sheets sit on QML-19500-31 NOT 1. VDSS spans up to 100 V and ID up to 48 A across the line, with hermetic packages including TO-254AA, TO-257AA, and hermetic SMD.5, plus JANHC / JANKC die versions for downstream MIL-PRF-38534 hybrid assembly.

Rad-hard Schottky diodes

ST manufactures space-grade Schottky rectifiers in hermetic ceramic and MELF packages, primarily in the 40 V to 150 V class with SEE characterization, addressing the same hermetic Schottky rectifier families widely used in secondary DC/DC power stages, current bypass, and reverse polarity protection. Most of these devices are marketed by ST under ESCC detailed specifications in the 5106/xxx series, with the same die stream available against MIL-PRF-19500 JAN-level purchase orders where a customer requires the JAN prefix.

Fast and superfast recovery rectifiers

Silicon rectifier diodes cover standard, fast, and superfast recovery devices, including the classic space-heritage superfast recovery rectifier family per /477 (MIL-PRF-19500/477) and companion families, along with 200–400 V power rectifier classes marketed under ESCC. These parts have decades of European launch and satellite flight heritage.

Hermetic switching diodes

ST's hermetic-glass switching-diode heritage runs through the 1N664x family of general-purpose silicon signal diodes, historically qualified against MIL-S-19500 and today shipped on the current MIL-PRF-19500 slash-sheet revisions in JAN through JANS product-assurance levels.

Unencapsulated die: JANHC and JANKC

For customers building their own MIL-PRF-38534 hybrid microcircuits and multichip modules, ST supplies its rad-hard MOSFET and bipolar lines at the chip-level (JANHC) and KGD (JANKC) product-assurance levels straight from the Rennes or Singapore wafer flow, with an ST specification issued alongside the JAN qualification.

Package heritage

Across these device families ST qualifies parts in a hermetic package inventory that includes axial-lead glass (DO-35, DO-41, DO-213AB/US MELF), metal-can (TO-18, TO-39/TO-5, TO-46, TO-78), space-optimized Flat-8 and Flat-16 hermetic ceramic, and rad-hard power packages TO-254AA, TO-257AA, and hermetic SMD.5 for the MOSFET line.

Space-flight heritage

STMicroelectronics traces its space involvement to 1977, when Thomson Semiconducteurs (a predecessor of ST) began supplying rad-hard discrete parts to European space programs. ST has been qualified by the European Space Agency since the ESCC system's inception and describes itself as having "over 40 years' commitment to space" and "millions of flying hours without failures." ST rad-hard bipolar transistors, power MOSFETs, Schottky rectifiers, and switching diodes are widely used across European launch systems, telecommunications and Earth-observation satellites, science missions coordinated by ESA and national space agencies, and, in the current commercial NewSpace generation, low-Earth-orbit constellations and small-satellite payload electronics. Specific program attribution is generally limited by prime-contractor confidentiality, but ST's rad-hard MOSFETs and JANS bipolars are common building blocks for satellite power distribution, motor drive, deployment mechanisms, and telemetry front ends.

Because rectifier and diode structures are naturally hard against Total Ionizing Dose effects up to roughly 10⁶ – 10⁷ rad(Si) and neutron fluences on the order of 10¹⁴ n/cm², MIL-PRF-19500 does not always specify an explicit RHA level on the diode side of the JANS portfolio — the parts are inherently rad-hard by construction. For active-device families — specifically the MOSFETs and bipolar transistors — ST carries formal RHA-graded JANS and JANSR product plus its wafer-by-wafer JANSR+ low-dose-rate guarantee for ELDRS-sensitive bipolar applications.

How Hybrid Electronics sources STMicroelectronics JAN parts

Hybrid Electronics Corporation is a Sanford, Florida-based independent stocking distributor and sourcing agent, founded in 1981 as Knight Electronics. We are not an authorized distributor, agent, licensee, or franchised partner of STMicroelectronics N.V. or STMicroelectronics S.A.S. What we do is help defense, aerospace, and industrial buyers close JAN-level BOMs when the mainstream authorized channel cannot support the exact date code, package variant, RHA level, or obsolete lot they need — including the ST rad-hard discrete parts that are hardest to schedule out of Rennes.

Obsolete and legacy JAN inventory

Discontinued SGS-Thomson-era and early-ST discrete part numbers, older date codes, and slash-sheet revisions no longer in current Rennes production. We source excess inventory from OEMs, contract manufacturers, and long-term storage stocks and can typically provide date-coded traceability.

Allocated current-production JAN parts

JANTXV, JANS, and JANSR rad-hard bipolars, MOSFETs, and rectifiers that are actively produced at Rennes but on long lead time or allocation. Send us a shortage list or a full BOM — we will confirm what we can source, in which package, at what RHA level, and with what lead time.

Slash-sheet and cross-reference sourcing

Have a MIL-PRF-19500 slash-sheet reference (e.g. /255, /391, /614, /630, /773) but no settled manufacturer part number? We can quote STMicroelectronics options and, where useful, cross to equivalent QPL-19500 sources from other qualified manufacturers, or between JANS and equivalent ESCC 5201/5202/5205/5106 part numbers.

Frequently asked questions

Is STMicroelectronics on the MIL-PRF-19500 QPL?

Yes. STMicroelectronics S.A.S. is on the current DLA Land and Maritime QML-19500 list under CAGE Code F8859, with the qualified line at 3, rue de Suisse, CS 60816, F-35208 Rennes Cedex 2, France, and a supporting wafer fab at STMicroelectronics Pte. Ltd., 28 Ang Mo Kio Industrial Park 2, Singapore. STMicroelectronics is one of the very few European manufacturers on the QML-19500 list, which is otherwise dominated by U.S. suppliers.

Why is STMicroelectronics listed as "S.A.S." on QML-19500?

S.A.S. stands for Société par actions simplifiée, a standard French private-company legal form. The DLA QPL entry is against the French operating entity STMicroelectronics S.A.S. because the Rennes, France site is the certified line for MIL-PRF-19500 discrete production, sitting inside ST's broader European space and hi-rel supply chain and running in parallel with the same site's ESCC and QML-V qualifications.

What JAN quality levels does STMicroelectronics hold on MIL-PRF-19500?

STMicroelectronics is qualified to JANTXV and JANS on its rad-hard MOSFET lines and to JANS and JANSR on its rad-hard bipolar transistor lines, with JANHC and JANKC die versions available for downstream hybrid assembly. On top of the standard JANSR wafer-lot high-dose-rate guarantee, ST's bipolar JANSR flow — sometimes marketed as "JANSR+" — adds a wafer-by-wafer 100 krad(Si) low-dose-rate test at 0.1 rad/s, identical to the ESCC 22900 guarantee, which addresses ELDRS effects in long-duration space missions.

Which MIL-PRF-19500 slash sheets is STMicroelectronics qualified against?

Widely cited ST slash sheets include /255 and /291 (small-signal bipolar transistor families), /391 (medium-voltage NPN transistors), /761 and /766 (high-voltage NPN and PNP families), /614 (N-channel rad-hard MOSFET families, on QML-19500-31 Notice 1), /630 (P-channel rad-hard MOSFET families at RHA levels R and F, on QML-19500-31 Notice 1), /773 (JANS2ST3360K-family dual complementary NPN+PNP Flat-8), and /477 (superfast recovery rectifier family).

What ST part families does Hybrid Electronics source?

Hybrid Electronics sources STMicroelectronics rad-hard discrete part families across JAN quality levels: JANS and JANSR NPN and PNP bipolar transistors (small-signal to 600 V), JANTXV and JANS rad-hard N-channel and P-channel MOSFETs, hermetic space Schottky diodes, fast and superfast recovery rectifiers, hermetic switching diodes, and hermetic dual complementary bipolar transistors. We work by exact part number and by MIL-PRF-19500 slash-sheet reference and support both current-production and obsolete legacy inventory.

Is Hybrid Electronics an authorized STMicroelectronics distributor?
