About Sensitron Semiconductor

Sensitron Semiconductor, founded in 1969 and headquartered in Deer Park, New York, is a privately held, family-owned manufacturer of high-reliability power semiconductors for U.S. military, aerospace, and space applications. With roughly 200 employees and a single vertically integrated Deer Park facility, Sensitron is a niche supplier — not a broadline commercial semiconductor house — focused on DSCC/MIL-PRF-19500 qualified discrete devices. Its portfolio spans general-purpose rectifier diodes, Schottky rectifiers, fast-recovery and ultrafast diodes, Zener diodes, transient voltage suppressors (TVS), silicon controlled rectifiers (SCRs / thyristors), bridge rectifiers from 1 A to 40 A, and hybrid power modules including full-wave bridges, high-current rectifier packs, and custom mil-spec assemblies — all built into hermetically sealed metal and ceramic packages qualified to JAN, JANTX, JANTXV, JANS, and ESA/QPL space-grade S-level screening flows.

Hybrid Electronics has channeled excess and legacy Sensitron product since we began sourcing in 1995. We support customers who need obsolete pre-1985 DO-4 stud-mount rectifiers for depot-level repair, older JANTX 2N1595 SCR revisions for fielded ordnance and power supplies, discontinued 15KP TVS series from pre-2010 lot codes, and hard-to-find legacy hermetic SMD SFM/SMH/SSH revs when authorized channels show zero stock or 40+ week lead times on JANS-level flows.

Sensitron product families we source

Our line card spans Sensitron's full portfolio — from current MIL-PRF-19500 JANTX and JANS diodes and rectifiers shipping into defense and aerospace primes, to legacy hermetic parts and rad-hard S-level flows still qualified into long-lifecycle space and mil programs.

General-Purpose Rectifiers — Through-Hole

SDA, SDB, and SDC series axial and stud-mount silicon rectifiers, plus the MIL-PRF-19500 qualified 1N540x family in JAN, JANTX, JANTXV, and JANS screening levels. Standard-recovery diodes to 1000 V PIV in hermetically sealed DO-4, DO-5, DO-13, and DO-41 packages for defense power-supply front ends.

General-Purpose Rectifiers — SMD Hermetic

SMH series surface-mount rectifier diodes in hermetically sealed ceramic SMD packages. Direct-solder replacements for legacy axial rectifiers in weight- and volume-constrained mil/aero and avionics assemblies.

Fast Recovery / Ultrafast — Through-Hole

SFR series fast- and ultrafast-recovery rectifiers, including the UF400x family and higher-current stud variants. Reverse-recovery times from 35 ns to 500 ns for switching regulators, motor drives, and inverter bridges in DSCC 19500-qualified flows.

Fast Recovery — SMD Hermetic

SFM series surface-mount fast-recovery diodes in hermetic ceramic SMD packages. Used across space-grade DC/DC converter designs and hi-rel switching front ends where plastic SMB/SMC packages cannot meet outgassing or hermeticity requirements.

Schottky Rectifiers — Through-Hole

SS series Schottky barrier rectifiers, including the mil-qualified 1N5817-1N5822 JANTX axial family, plus higher-current stud-mount variants. Low-Vf devices for battery-fed avionics, ground-support equipment, and payload power distribution.

Schottky Rectifiers — SMD Hermetic

SSH series hermetic surface-mount Schottky rectifiers. Ceramic-sealed alternatives to commercial SMA/SMB plastic parts for missile electronics, satellite bus power, and radiation-tolerant point-of-load converters.

Zener Diodes — Voltage Reference

SZ series Zener regulator diodes covering the 1N746 JANTX through 1N4740 JANTXV ranges, plus higher-power stud packages. Precision voltage-reference and overvoltage-clamp devices for regulated power supplies in DSCC MIL-PRF-19500 flows.

TVS Diodes — High-Reliability

STVS series transient voltage suppressors and the mil-qualified TVS 15KP JANTX family for high-energy transient clamping. Bidirectional and unidirectional variants from 5 V to 250 V standoff, rated for MIL-STD-704 and MIL-STD-1275 avionics and vehicle-bus surge protection.

Bridge Rectifiers — 1 A to 40 A

SBR series single-phase and three-phase bridge rectifiers, plus the MDA-JAN qualified family in stud and hockey-puck packages. Full-wave and half-wave bridges from 1 A to 40 A for mil-spec ground power, shipboard, and aircraft DC-generation subsystems.

Thyristors & SCRs — Mil-Qualified

SS and SR series silicon-controlled rectifiers, plus the DSCC-qualified 2N series (2N1595, 2N4441 JANTXV, 2N681, 2N1849) in hermetic TO-5, TO-48, and stud packages. Phase-controlled rectification and crowbar overvoltage protection for defense inverters and power-supply front ends.

Hybrid Power Modules & Custom Assemblies

Sensitron-built hybrid full-wave bridges, high-current rectifier packs, and custom mil-spec power assemblies combining multiple die into hermetically sealed metal packages. Built to customer SCDs (Source Control Drawings) with full MIL-STD-883 element evaluation and screening.

Space-Grade — S-Level & ESA/QPL

Radiation-hardened and space-qualified versions of the SDA, SFR, SS, STVS, and 2N SCR families to MIL-PRF-19500 JANS, MIL-STD-883 Class S, and ESA/QPL flows. Total-dose (TID) and single-event effect (SEE) characterized parts for LEO/GEO satellite and launch-vehicle avionics.

Additional Sensitron rad-hard S-level rectifiers, TVS arrays, and custom hybrid mil-spec modules quoted on request. All parts are subject to MIL-PRF-19500 lot acceptance testing, DPA availability, and full traceability — ITAR/EAR export screening applies to defense-controlled shipments.

Obsolete & hard-to-find Sensitron parts

Sensitron's mil-spec catalog has evolved for over five decades, and older QPL revisions, hermetic package styles, and lot codes leave the active DSCC-qualified line as new revs are released. Defense depots, sustainment contractors, and long-lifecycle space programs regularly need continued access to obsolete Sensitron devices. Hybrid Electronics sources these end-of-life and legacy parts from OEM excess, contract-manufacturer surplus, and traceable secondary channels:

Send an RFQ with quantity, target date code range, screening level (JAN / JANTX / JANTXV / JANS), and any traceability requirements (COC, DPA, lot cert) — we return same-day availability from stock or an ETA from our sourcing network.

Sensitron quote & sourcing FAQ

What Sensitron products does Hybrid Electronics quote most often?

MIL-PRF-19500 JANTX and JANTXV axial rectifiers (1N4001-1N4007, 1N5400-1N5408, 1N5817-1N5822 Schottky), UF400x ultrafast diodes, 15KP TVS transient suppressors, and 2N1595 / 2N4441 SCRs are our highest-volume Sensitron quote categories. Legacy DO-4 stud rectifiers, pre-2010 15KP TVS lots, and JANS space-level parts for satellite programs are steady low-volume sourcing lines.

Are Sensitron parts DSCC / MIL-PRF-19500 qualified?

Yes — Sensitron Semiconductor is a DSCC-qualified manufacturer under MIL-PRF-19500, the U.S. mil-spec for discrete semiconductors. Their catalog spans JAN (Level 3), JANTX (Level 2), JANTXV (Level 1), and JANS (Space) screening flows, plus MIL-STD-883 Class S element-evaluation and ESA/QPL space-grade parts for satellite and launch-vehicle avionics.

Can Hybrid Electronics source JANS space-level and rad-hard Sensitron parts?

Yes — on an inquiry basis. JANS-qualified parts (1N5817JANS, SDC40-10JANS, STVS15-28CJANS, SR3-08JANS, SZ5.1CJANS and similar) require lot-specific traceability and often single-lot delivery to space programs. Include your target quantity, required date code window, and any DPA / element-evaluation requirements on the RFQ, and we will return an availability window and quoted price against OEM excess and traceable channel stock.

Do you support ITAR / EAR export-controlled Sensitron shipments?

Yes — Sensitron parts qualified to MIL-PRF-19500 for defense and space applications are commonly subject to U.S. export controls (EAR ECCNs including 3A001 for certain rad-hard devices and ITAR §121 for defense-articles-integrated shipments). Hybrid Electronics screens every export order for end-use, end-user, and destination compliance under EAR §744 and the ITAR. AES/ITN filing is included on qualified export shipments.

How fast is your Sensitron quote turnaround?

Same day for parts in stock — typically within 2 hours during business hours (9am–6pm ET). Sourced quotes on out-of-stock parts return within 24–48 hours with an availability window. Email sales@hybridelectronics.com or call (407) 542-3995 to open an RFQ.

Is Hybrid Electronics an authorized Sensitron Semiconductor distributor?

No — we're an independent distributor and excess-inventory buyer sourcing from OEM excess, CEM surplus, and traceable secondary channels since 1995. For factory-warranted current-production orders, work with a Sensitron-authorized distributor. For obsolete, hard-to-find, JANS space-level, or allocated Sensitron parts where authorized channels show no stock, Hybrid Electronics is a proven independent source.
