MIL-PRF-19500 — JAN, JANTX, JANTXV & JANS discrete semiconductor manufacturers
MIL-PRF-19500 is the U.S. Department of Defense performance specification for hermetically-sealed discrete semiconductor devices — diodes, rectifiers, transistors, thyristors, SCRs, TVS devices, and hermetic optoelectronics — administered by the Defense Logistics Agency (DLA) Land and Maritime, Columbus OH. Roughly seventeen manufacturer plants currently hold active qualification on the QML-19500. Below is our working directory of both current QML holders and historic / legacy JAN brands whose parts remain in the defense and space supply chain. Hybrid Electronics sources across all quality levels — JAN, JANTX, JANTXV, JANS, and JANSR.

MIL-PRF-19500 quality levels at a glance
| Level | Screening added over baseline | Typical use |
|---|---|---|
| JAN | Baseline joint army-navy qualification per MIL-PRF-19500 | Ground / airborne / general defense |
| JANTX | Adds 168-hour burn-in and additional 100% electrical screening | Mission-critical airborne, tactical |
| JANTXV | Adds pre-cap visual inspection (100%) to JANTX flow | High-reliability airborne, avionics |
| JANS | Space level — 100% additional screening, wafer lot acceptance testing (WLAT), SEM inspection | Satellite, launch vehicle, deep space |
| JANSR | JANS plus radiation lot acceptance testing (RLAT) at specified TID levels | Rad-hard space, GEO, deep space |
| JANHC / JANKC | Chip / bare-die level qualification for hybrid microcircuit integration | MIL-PRF-38534 hybrid assemblies |
Historic and legacy JAN brands
Legacy manufacturers whose JAN parts remain in the defense supply chain. Many were consolidated into current QML holders, but original-marked stock is still specified and searched.
What Hybrid sources under MIL-PRF-19500
Hybrid Electronics operates as an independent stocking distributor and sourcing agent for the defense and aerospace supply chain. Under MIL-PRF-19500, we support programs across all quality levels:
- Silicon rectifiers — standard, fast, ultrafast, hyperfast, and high-voltage rectifier families in axial, SMD, and MELF hermetic packages
- Schottky rectifiers — low-VF Schottky per /620 and related slash sheets, silicon and SiC
- Zener and voltage-reference diodes — precision zeners with 0.05 %–1 % voltage tolerance in hermetic glass
- TVS (Transient Voltage Suppressor) devices — uni- and bidirectional TVS per /516 for line-side protection
- Bipolar transistors — small-signal NPN/PNP, medium-voltage, high-voltage per /255, /291, /391, /761, /766 families
- Power MOSFETs — N- and P-channel rad-tolerant and rad-hard MOSFETs per /652, /657, /660, /664, /685, /704, /707 and related
- GaN power transistors — rad-hard eGaN FETs qualified to JANS/JANSR (newest addition to the specification)
- Thyristors, SCRs, and TRIACs — hermetic high-power switches
- Hermetic optoelectronics — opto-isolators, LEDs, photologic sensors, photodiodes per /519, /520, /521, /548
- Rad-hard hybrid modules — related hybrids under MIL-PRF-38534 that integrate MIL-PRF-19500 discretes
We work by exact JAN part number and by MIL-PRF-19500 slash-sheet reference. We support current-production parts, obsolete and end-of-life legacy inventory, and short-lead alternates against the same JAN quality level.
Sourcing an MIL-PRF-19500 part?
Send us the JAN part number, slash sheet, or drawing reference. We source across all quality levels — JAN through JANSR — from current QML manufacturers and the excess-inventory market.
