About Solitron Devices

Solitron Devices, Incorporated was incorporated under the laws of the State of New York in March 1959 and reincorporated in Delaware in August 1987. The company's original manufacturing home was Tappan, New York, where Solitron operated a discrete-semiconductor production facility from 1961 through 1987 before consolidating in South Florida. Today Solitron's corporate headquarters, wafer fab, assembly line, packaging, electrical test, and environmental screening operations are all located under one roof at 901 Sansburys Way, West Palm Beach, Florida 33411 — a purpose-built facility the company moved into after outgrowing its previous 3301 Electronics Way West Palm Beach plant.

Solitron is one of a very small number of MIL-PRF-19500 manufacturers that is independent and publicly traded. Common stock trades on the OTC Pink market under the ticker SODI, and the company files annual and quarterly reports with the U.S. Securities and Exchange Commission under Commission File No. 001-04978. Solitron's SEC filings describe it as designing, developing, manufacturing and marketing solid-state semiconductor components and related devices primarily for the military and aerospace markets. In fiscal year 2025 (ended February 28, 2025), Solitron reported net sales of approximately $14.05 million, up about 10% year-on-year, with a product mix of 43% power transistors, 33% hybrids, 15% power MOSFETs, 8% field-effect transistors, and 1% wafers/dice, and roughly 96% of sales coming from custom-engineered high-reliability parts.

Solitron sells into ground and airborne radar systems, power distribution systems, missiles, missile-control electronics, satellites, and space applications, as well as adjacent industrial and scientific programs. The company's West Palm Beach facility is certified against MIL-PRF-19500 for JAN/JANTX/JANTXV product-assurance levels, MIL-PRF-38534 Class H for hybrid microcircuits, AS9100 Rev D, and ISO 9001:2015, and also builds to customer-supplied source control drawings and to commercial off-the-shelf (COTS) standards. Solitron additionally offers a "JAN S" / S-level equivalent screening flow for space-grade parts on request, running its standard 19500 devices through 340-hour stabilization bake, 20 temperature cycles from −65 °C to +175 °C, and sinusoidal current surge steps out of MIL-STD-750.

QPL / QML-19500 status

The Defense Logistics Agency (DLA) Land and Maritime real-time list of qualified sources for MIL-PRF-19500 currently shows Solitron Devices Incorporated as an active qualified source under CAGE Code 21845, with three registered plant locations:

  • Solitron Devices Incorporated — 901 Sansburys Way, West Palm Beach, FL 33411, US (primary manufacturer location and corporate HQ)
  • Solitron Devices Incorporated (plant #2) — 1177 Blue Heron Boulevard, Riviera Beach, FL 33404, US
  • Solitron Devices Incorporated (plant #3) — Bourns Ltd., Manton Lane, Bedford, UK MK41 7BJ

The Riviera Beach and Bedford entries reflect Solitron's network of sub-tier and packaging partners that participate in the DLA-audited flow. All three addresses roll up to the single manufacturer CAGE Code 21845. Additional Solitron-owned CAGE codes on record with DLA/SAM include 4K930, 1D667, 5R465, 8L228, and 13327 — buyers should be aware that older QPL-19500 revisions cite a Solitron address at 3301 Electronics Way, West Palm Beach, FL 33407 and, earlier still, at 1177 Blue Heron Boulevard, Riviera Beach, FL 33404. Those older-address parts are the same JAN/JANTX/JANTXV product line under continuous certification — only the manufacturing address on the DLA record has changed.

Solitron's footprint on MIL-PRF-19500 is best known for two things: it is described by third-party distributors as the "world's leading manufacturer of standard QPL JAN/JANTX/JANTXV small-signal JFETs", and it is one of a handful of U.S. manufacturers producing rad-hard 500–1200 V hermetic power MOSFETs — including the industry's first military-grade 700 V silicon-carbide (SiC) MOSFET, announced in 2019. Combined with its MIL-PRF-38534 Class H hybrid line, Solitron holds roughly 200 DLA-qualified device types across the two specifications.

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

MIL-PRF-19500 is the U.S. Department of Defense performance specification for hermetically-sealed discrete semiconductor devices — diodes, rectifiers, bipolar transistors, field-effect transistors, thyristors, silicon controlled rectifiers (SCRs), and transient voltage suppressors (TVS). It is 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
JANHC / JANKC Chip / die-level Unencapsulated die screening for downstream hybrid assembly MIL-PRF-38534 hybrids, custom modules

Solitron's standard DLA qualification on MIL-PRF-19500 covers the JAN, JANTX, and JANTXV levels. On top of that, Solitron publishes its own "JAN S" screening flow that mirrors the JANS product-assurance steps — 340-hour stabilization bake at maximum operating temperature, 20 temperature cycles from −65 °C to +175 °C, and sinusoidal current surge per MIL-STD-750 — and applies it to standard JAN/JANTX/JANTXV parts on request for S-level equivalent screening. For JANS-flagged parts specifically, MIL-PRF-19500 also defines eight Radiation Hardness Assurance (RHA) levels (M, D, P, L, R, F, G, H) that correspond to Total Ionizing Dose (TID) guarantees ranging from 3 krad(Si) up to 1 Mrad(Si). On top of individual part-type qualification (the older Qualified Products List, QPL), the DoD now operates a line-level certification model called the Qualified Manufacturers List (QML), which is the framework the Solitron West Palm Beach line is certified against.

Solitron's MIL-PRF-19500 product portfolio

Solitron is a power-discrete house. Its DLA-qualified portfolio is anchored in small-signal JFETs and 2N-series bipolar power transistors that have been on the QPL-19500 list for decades, and it has extended that base into a modern rad-hard silicon and silicon-carbide power MOSFET line for space and airborne systems. 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.

Small-signal JFETs (N-channel and P-channel)

Solitron is described as the world's leading manufacturer of standard QPL JAN/JANTX/JANTXV small-signal junction field-effect transistors. The line features low on-resistance, low capacitance, good input isolation, fast switching, high inherent radiation tolerance, and S-level processing for satellite payload electronics. Representative slash-sheet coverage:

  • /296 — P-channel small-signal JFETs, TO-18 hermetic
  • /375 — N-channel small-signal JFETs, TO-72 hermetic
  • /385 — N-channel small-signal JFETs, TO-18 hermetic
  • /476 — P-channel small-signal JFETs, TO-18 hermetic

Bipolar power transistors (2N-series)

Solitron's hermetic bipolar power transistor line covers JAN, JANTX, and JANTXV product-assurance levels across a wide package inventory — TO-3, TO-5/TO-39, TO-11, TO-66, TO-111/I, and TO-114. Both NPN and PNP topologies are qualified and are widely stocked into avionics, missile, radar, and ruggedized industrial platforms. Standard-catalog 2N part numbers make up a large share of Solitron's FY2025 sales mix (43% of revenue was power transistors).

Rad-hard hermetic power MOSFETs (silicon and silicon carbide)

Solitron manufactures N-channel silicon power MOSFETs from 500 V to 1000 V and N-channel silicon-carbide (SiC) power MOSFETs from 700 V to 1200 V, with matching P-channel devices. Parts are offered in hermetic TO-254, TO-257, TO-258 3-lead and related power packages, with 200 °C operation available on selected devices, and are screened to MIL-PRF-19500 or MIL-PRF-38534 as required by the customer. The line is positioned as SEGR-resistant / rad-hard for satellite power distribution, motor drive, and payload electronics. Solitron announced the industry's first military-grade 700 V, 15 mΩ silicon-carbide MOSFET in 2019 as part of this family.

Thyristors, SCRs and high-voltage rectifiers

Solitron's DLA-qualified line also includes JAN thyristors, JAN silicon controlled rectifiers (SCRs), and hermetic high-voltage rectifiers for military power switching and conversion applications. These families are commonly cross-referenced against MIL-PRF-19500 slash-sheet numbers on OEM BOMs and are supported alongside the JFET and transistor portfolio on the same qualified line.

JAN diodes and Standard Military Drawings voltage regulators

The company's standard/catalog line includes JAN transistors, JAN diodes, and Standard Military Drawings (SMD, DLA 5962- and 8-series) voltage regulators. These sit on the standard-product side of the P&L (roughly 4% of FY2025 sales, with 96% coming from custom-engineered designs).

Adjacent MIL-PRF-38534 Class H hybrid line

Alongside the discrete MIL-PRF-19500 flow, the same West Palm Beach facility produces MIL-PRF-38534 Class H hybrid microcircuits — DC-to-DC converters (custom and standard), motor drivers and motor controllers, power operational amplifiers, power controllers, power-factor-correction modules, and rad-hard SEGR- resistant hybrid assemblies. Solitron builds those hybrids using its own JAN-level discrete die, closing the loop from wafer to space-grade power module inside one vertically integrated facility.

Space, missile & defense heritage

Solitron's discrete and hybrid parts have flown on U.S. defense and space platforms since the company's Tappan, New York era in the 1960s and 1970s. The company's current SEC 10-K filings describe end-use applications spanning ground and airborne radar systems, power distribution systems, missiles, missile-control systems, satellites, and space applications, alongside adjacent commercial, scientific, and industrial programs. In practice, Solitron's parts most commonly appear on military power buses, avionics motor-drive electronics, phased-array radar power conditioning, missile-seeker electronics, and satellite payload power distribution.

Because JFET and bipolar structures are naturally tolerant to Total Ionizing Dose and neutron fluences at levels that comfortably exceed most avionics missions, Solitron's small-signal JFETs and 2N-series bipolar power transistors are widely designed into satellite payload analog signal chains and rad-tolerant amplifier front-ends without needing an explicit RHA level. For active power switching, the newer rad-hard hermetic silicon and silicon-carbide MOSFET line addresses Single Event Gate Rupture (SEGR) and single-event burnout hardness — making Solitron one of the very few U.S. sources of qualified military-grade SiC MOSFETs for high-orbit and deep-space power electronics.

How Hybrid Electronics sources Solitron 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 Solitron Devices, Incorporated. 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, or obsolete lot they need.

Obsolete and legacy JAN inventory

Discontinued small-signal JFET and 2N-series bipolar transistor date codes, legacy 3301 Electronics Way and Riviera Beach-era Solitron marking, and older slash-sheet revisions no longer in current 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

JAN, JANTX, and JANTXV parts that Solitron is actively producing but that are on long lead time or allocation — particularly rad-hard MOSFETs and custom power hybrids. Send us a shortage list or full BOM and we will confirm what we can source, in which package, and at what lead time.

Slash-sheet and cross-reference sourcing

Have a MIL-PRF-19500 slash-sheet reference (e.g. /296, /375, /385, /476) but not a settled manufacturer part number? We can quote Solitron options and, where useful, cross to equivalent QPL-19500 sources from other qualified manufacturers.
