About Sensitron Semiconductor
Sensitron Semiconductor is the operating brand of RSM Electron Power, Inc., a privately-held Long Island small business founded in 1969. The company operates two facilities: the corporate headquarters and Microelectronics Group at 100 Engineers Road, Hauppauge, NY 11788, and the Discrete Semiconductor Group — the plant behind the MIL-PRF-19500 QML line — at 221 West Industry Court, Deer Park, NY 11729-4681. The Deer Park facility is registered with DLA under CAGE Code 13409; the Hauppauge address carries the sibling CAGE Code 779K2. Both facilities are AS9100 Rev C registered and ISO 9001 certified.
Sensitron sits in an unusual niche on the MIL-PRF-19500 landscape. Unlike the very large “pure” discrete houses that dominate the JAN diode QPL by part-number count, Sensitron is a vertically-integrated high-reliability power-electronics manufacturer that produces its own diode wafers, screens and cases them to JAN, JANTX, JANTXV and JANS product-assurance levels, and then, on the same site, packages many of them into MIL-PRF-38534 Class H and Class K hybrid modules — bridges, rad-hard MOSFET assemblies, motor controllers, intelligent power modules, lightning-strike protection modules and MIL-STD-1275 Transorbs. That combination is why Sensitron is designed into so many aerospace generator, satellite power-distribution, missile power-conditioning and airborne motor-drive electronics assemblies.
Sensitron describes its addressable markets as Defense, Aerospace, Space and Medical, and it maintains worldwide sales and distribution support out of Long Island. The company's public materials cite flight heritage across the International Space Station, GPS III, Galileo, Iridium, Globalstar, Advanced EHF, Space-Based Radar, Mars Orbiter & Lander, TerraSAR, Titan, Atlas / Atlas V URCU and BRCU, EchoStar, DirecTV, Intelsat, Sirius, Space Tech 5, Spacebus 3000/4000, Galaxy 12/14/15, Eurostar 3000, the National Polar-Orbiting Satellite Systems, NextView and ASTRO15, alongside airborne and missile-defense platforms — more than three million JANS and JANS-equivalent diodes shipped to space applications by Sensitron's own count.
QPL / QML-19500 status
The Defense Logistics Agency (DLA) Land and Maritime real-time list of qualified sources for MIL-PRF-19500 currently shows Sensitron under a single active entry:
- Sensitron Semiconductor — 221 West Industry Court, Deer Park, NY 11729, US — CAGE Code 13409
Sensitron has publicly stated that its QML-19500 footprint covers approximately twenty individual slash sheets at the JANTXV/JANS level, encompassing more than 250 JANS part numbers with additional slash sheets being added every quarter. The company supplied JANS-equivalent axial and MELF diodes for ten-plus years before receiving formal JANS qualification in 2011, and it also holds JANHC and JANKC unencapsulated-die qualifications for customers building their own MIL-PRF-38534 hybrids.
Two more-recent QPL milestones anchor the current portfolio. In an earlier award, DLA granted Sensitron QPL status on MIL-PRF-19500/469 for 10-amp single-phase bridge rectifiers. Sensitron subsequently added QPL status on MIL-PRF-19500/483 for 25-amp three-phase bridge rectifiers, covering the /483-01, /483-02 and /483-03 configurations. Sensitron's current Notification of Qualification Extension VQE-19-034190, issued by DLA on August 7, 2019 against MIL-PRF-19500P Amendment 4, refreshes its JANHC and JANKC die-level qualifications and confirms the Deer Park line in continuous good standing on the QML.
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, 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 |
| JANHC / JANKC | Chip / die-level | Unencapsulated die screening for downstream hybrid assembly | MIL-PRF-38534 hybrids, custom modules |
For JANS parts, MIL-PRF-19500 further defines eight Radiation Hardness Assurance (RHA) levels, encoded as a single character (M, D, P, L, R, F, G, or H) inserted into the part number just after the JANS prefix. Those characters correspond to Total Ionizing Dose (TID) guarantees ranging from 3 krad(Si) at “M” up to 1 Mrad(Si) at “H.” On top of the 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 Sensitron's Deer Park facility is certified against.
Sensitron's MIL-PRF-19500 product portfolio
Sensitron's hermetic discrete portfolio is deliberately deep on the diode side and then extended into hybrid power modules under MIL-PRF-38534. The categories below are all covered by current QML-19500 qualifications at Deer Park and are the families we most commonly source. 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.
Standard, fast, and ultrafast rectifier diodes
Sensitron holds JANTXV/JANS qualification across the full recovery-speed range on axial and MELF packages. Representative slash sheets include /228 and /286 (1 A general purpose recovery), /420 and /427 (1 A and 3 A standard recovery), /359, /411, /424 and /429 (1 A and 3 A fast recovery), and /477, /478, /585 and /590 (1 A, 2 A, 3 A and 20 A ultrafast recovery, including 20 A DO-4 devices). MELF surface-mount equivalents typically carry the “US” or “U” suffix.
Zener voltage regulators
Sensitron's zener families cover 500 mW, 1.5 W and 5 W power ratings from 6.2 V through 390 V. Key slash sheets include /117 and /127 (500 mW zener die), /406 (1.5 W hermetic zener regulators with JAN through JANS levels), /356 (5 W zener voltage regulators), /435 (500 mW axial) and /533 (500 mW MELF).
Schottky diodes — silicon and SiC
Sensitron is qualified against slash sheet /444 (small-signal Schottky die family), /586 (1 A/45 V axial Schottky) and the /620 Schottky series. The commercial-catalog Schottky line extends from 15 V/1 A up to 200 V/120 A on silicon, with a broad Silicon Carbide Schottky lineup up to 2500 V in through-hole (TO-254, TO-257, TO-258) and surface-mount (SMD, LCC) hermetic and ceramic-seal packages, screenable to JANS-equivalent flows.
Transient Voltage Suppressors (TVS)
Hermetic TVS is one of Sensitron's deepest QPL categories, spanning /500 (1500 W unipolar TVS in DO-13), /507 (1500 W bidirectional TVS in DO-13), /516 (500 W bidirectional TVS in MELF with both standard and “A” 5%-tolerance versions from 10 V to 152 V working voltage), and /772 (150 W / 500 W / 1500 W unipolar TVS). Product-assurance levels run up to JANS with wafer-lot control.
Small-signal switching diodes
Sensitron carries the workhorse hermetic switching families on slash sheets /116 (die-level JANHCC/JANKCC switching diodes), /169, /578 and /609, in both axial and MELF packages, up to JANS.
Single- and three-phase bridge rectifiers
Sensitron's bridge-rectifier QPL entries are a distinguishing part of its 19500 footprint. MIL-PRF-19500/469 covers 10 A single-phase hermetic bridges. MIL-PRF-19500/483, added more recently, covers 25 A three-phase hermetic bridge rectifiers across the /483-01, /483-02 and /483-03 variants.
Unencapsulated die: JANHC and JANKC
For customers building their own MIL-PRF-38534 hybrid microcircuits, Sensitron supplies its switching, Zener, ultrafast rectifier, TVS and Schottky dies at the chip-level (JANHC) and KGD (JANKC) product-assurance levels straight from the wafer, on slash sheets including /116, /117, /127, /169, /444, /477, /533, /578, /586 and /609. Front-metal (Al, Ag or Au) and back-metal (Ag or Au) options are stocked to fit customers' wire-bond and solder-attach flows.
Packaging heritage
Sensitron qualifies these device families across axial-lead hermetic glass (DO-4, DO-7, DO-13, DO-35, DO-41), surface-mount MELF (with “US” and “U” suffixes), miniature power surface-mount packages including patented high-strength SMD-0.2 and SMD-0.5 rugged bodies, and through-hole metal-can and ceramic power packages (TO-254, TO-257, TO-258, LCC-3P, LCC-5, SCB-2) for the SiC and rad-hard MOSFET families.
Beyond MIL-PRF-19500 — Sensitron's MIL-PRF-38534 hybrid power modules
What makes Sensitron distinctive versus most of its peers on the QML-19500 is the second line of qualification it carries alongside the discrete diode QPL: MIL-PRF-38534 Class H and Class K for hybrid microcircuits. That flow is what allows Sensitron to package its JANHC/JANKC dies and third-party rad-hard silicon into rad-hard power modules, IGBT and MOSFET bridges, high-power rectifier assemblies and complete motor-drive modules that are screened and lot-accepted to space-grade quality.
Rad-hard MOSFET modules — SRADM series
The SRADM radiation-hardened N-channel power MOSFET line is offered in single-MOSFET, three-phase bridge and quad-array hybrid configurations. Total Ionizing Dose hardness is 100 krad(Si) as standard with 300 krad(Si) available on request. Single-Event Effects hardness has been characterized up to LET 55 at 90 µm using Xe and NASA-tested to LET 85 at 118 µm using Au. Target applications are buck-boost and switch-mode converters, DC/DC power stages, and H-Bridge motor drives.
Half-bridge, full-bridge and three-phase IGBT / MOSFET modules
Sensitron builds hermetic and near-hermetic power bridges spanning silicon IGBTs, silicon MOSFETs and SiC devices. Representative modules include the SCP-5115i high-power half-bridge IGBT module (600 V, 1200 A) with creepage and clearance optimized for altitude, the SCM1001 three-phase IGBT/SCR assembly (1200 V, 150 A three-phase IGBT bridge plus 1200 V/57 A half-controlled SCR bridge with 63 A diodes and upper/lower regenerative brake switches on an AlSiC baseplate), the SBM series three-phase IGBT bridges with integrated gate driver (600 V–1200 V up to 250 A, 2500 V isolation to baseplate), and the lightweight SPx10xx three-phase power bridge modules in silicon or SiC (up to 1200 V, 15 A–150 A) built for −65 °C to +175 °C harsh-environment operation.
High-power rectifier bridge and rotating rectifier assemblies
The SBR series of three-phase full-wave bridge rectifiers extends up to 1400 V PIV and 45 A–360 A output over the −65 °C to +150 °C range, with 1.5 kV–2.5 kV AC isolation to baseplate and direct-mount thermal design for commercial aircraft. Sensitron also builds rotating rectifier assemblies for aerospace and defense generators, rated up to 1000 V, 120 A and 27,500 RPM operating (35,000 RPM mechanical), with 175 °C maximum operating temperature and compatibility with airborne oils and fluids.
Motor controllers and intelligent power modules
The SMC6 / SMCT6 / SMCS6 series are fully-integrated analog three-phase BLDC motor controllers designed for applications from 800 W up to 1200 V, 150 A, offered in hermetic and non-hermetic packages with speed, sensorless and torque modes. The SMCV and SECV digital series add field-oriented control with near-sinusoidal phase currents, RS-232 or CAN interfaces, top speeds over 70,000 RPM, and reconfigurable firmware. The SPM6 Intelligent Power Modules integrate MOSFETs (100 V–600 V up to 150 A) or IGBTs (600 V–1200 V up to 140 A) with isolated I/O, baseplate temperature and current reporting, and overtemperature, overcurrent and desaturation protection.
Lightning-strike protection and MIL-STD-1275 Transorbs
The LSP series of lightning-strike protection modules is 100% tested to DO-160 Section 22, Levels 4 and 5, Waveforms 5A and 5B, with peak currents from 750 A up to 20,000 A. The SCP-5282-x SuperClamp Transorb family provides MIL-STD-1275 28 V vehicle transient protection with clamping below 40 VDC on 100 V and 250 V pulses, while the SAE-5282-12 and SCP-1275 cover 12 V SAE J1113-11 and the full MIL-STD-1275 waveform respectively.
Space, missile and airborne flight heritage
Sensitron's discrete diodes and hybrid power modules have been designed into a wide range of U.S. and allied space missions and defense platforms. Publicly-cited flight heritage includes the International Space Station, GPS III, Galileo, Iridium, Globalstar, Advanced EHF, Space-Based Radar, Mars Orbiter & Lander (including the Dawn satellite camera), TerraSAR, Titan and Atlas / Atlas V URCU and BRCU, EchoStar, DirecTV, Intelsat, Sirius, Space Tech 5, the Spacebus 3000/4000 and Galaxy 12/14/15 commercial platforms, Eurostar 3000, the National Polar-Orbiting Satellite Systems, NextView and ASTRO15, alongside a broad set of missile-defense and airborne motor-drive platforms.
Sensitron states that it has shipped more than 3 million JANS and JANS-equivalent diodes to space applications and that its parts have a “10-year pedigree” on those programs. On the active-device side, the SRADM radiation-hardened MOSFET family is TID-hardened to 100 krad (300 krad on request) and characterized against Single-Event Latch-up, Single-Event Burnout and Single-Event Gate Rupture up to LET 85 under NASA testing, which makes it a common choice for satellite power distribution, motor drive and payload electronics.
How Hybrid Electronics sources Sensitron 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 Sensitron Semiconductor or RSM Electron Power, Inc.
