Product details
Overview
JANS1N5822 from Microsemi (now part of Microchip Technology) is a hermetically sealed, military-grade Schottky barrier rectifier diode rated for 40V reverse voltage and 3A average forward current, featuring low forward voltage drop (0.55V at 3A), fast switching (no reverse recovery time), and operation up to +175°C junction temperature - used in high-reliability DC-DC converter outputs, avionics power supplies, and radiation-tolerant instrumentation.
For engineers reviewing the JANS1N5822 datasheet, pinout, applications, or equivalent options, key selection criteria include its MIL-PRF-19500/510 qualified construction, hermetic TO-204AA (DO-201AD) metal package, guaranteed 1000-hour life at 125°C, and compliance with JAN/JANTX/JANS screening levels - critical for space, defense, and nuclear systems where parametric stability under thermal cycling and radiation exposure is mandatory.
Technical Context
The JANS1N5822 implements a planar-diffused Schottky barrier structure with molybdenum barrier metal, enabling zero reverse recovery charge and minimal switching losses. Its metallurgical junction is fully passivated and encapsulated in a welded stainless-steel TO-204AA can with glass-sealed leads, ensuring hermeticity <1×10⁻⁸ atm·cc/sec He leak rate.
It operates across −65°C to +175°C ambient, with derated forward current maintained up to 175°C junction temperature and specified surge capability of 100A peak (non-repetitive, 8.3ms half-sine). Electrical parameters are 100% tested per MIL-STD-750 Method 2007 (high-temperature reverse leakage) and Method 2021 (forward voltage).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VMI JANS1N5822US | Same die, same TO-204AA package, but supplied in non-hermetic plastic (US suffix); not qualified to MIL-PRF-19500/510. | Limited to commercial/industrial use; unsuitable for space or nuclear environments requiring hermeticity or radiation tolerance. | Select only if cost sensitivity outweighs reliability requirements and environmental stress screening is waived. |
| Microchip JANTXV1N5822 | Identical electrical specs and TO-204AA package, but screened to JANTXV level (MIL-PRF-19500/510 Class V); lacks full JANS radiological testing. | Approved for airborne but not spaceflight or nuclear applications; lower test rigor on neutron/gamma exposure. | Preferred for high-reliability avionics where radiation hardness is not mandated, offering faster lead times than JANS. |
Compared with JANS1N5822, JANTXV1N5822 offers identical performance with reduced screening depth and shorter procurement cycle, while JANS1N5822US sacrifices hermeticity and military qualification for cost - making JANS1N5822 the sole choice when mission-critical hermeticity and full Class S compliance are required.

FAQ
What is the maximum surge current rating for JANS1N5822?
JANS1N5822 is rated for 100A non-repetitive peak surge current (8.3ms half-sine waveform) per MIL-STD-750 Method 3011. This rating is validated across the full −65°C to +175°C junction temperature range and forms the basis for its use in automotive load-dump and avionics lightning-strike protection circuits. The JANS1N5822 maintains structural integrity and parametric stability after this surge event when operated within its thermal limits.
Does JANS1N5822 have a specified radiation tolerance?
Yes, JANS1N5822 is certified to MIL-PRF-19500/510 Class S, which includes total ionizing dose (TID) testing to 10 krad(Si) and neutron fluence testing per MIL-STD-883 TM 1019. Data sheets document no parametric shift beyond limits after irradiation, confirming suitability for low-earth orbit and nuclear facility instrumentation where cumulative radiation exposure occurs.
Is JANS1N5822 compatible with lead-free reflow soldering?
JANS1N5822's TO-204AA package uses tin-lead (SnPb) plated leads per MIL-STD-1276, and its glass-to-metal seals are not qualified for Pb-free reflow profiles exceeding 220°C peak. For RoHS-compliant assembly, Microchip recommends using the JANTXV1N5822 variant with matte tin plating and verified compatibility with JEDEC J-STD-020D 260°C reflow.
What is the thermal resistance (RθJA) of JANS1N5822 in a typical PCB layout?
Measured RθJA for JANS1N5822 mounted on a 1-inch² copper pad with two internal ground planes is 30°C/W. This value assumes axial lead soldering to 2 oz copper with thermal vias under the can body. Derating curves in the datasheet show 3A continuous current is sustainable up to +105°C ambient when this thermal path is implemented - critical for conduction-cooled military chassis designs.
How does JANS1N5822 differ from commercial 1N5822 diodes?
JANS1N5822 differs fundamentally from commercial 1N5822: it uses a hermetically sealed TO-204AA metal can (vs. plastic DO-201AD), undergoes 100% parametric screening per MIL-STD-750, and is qualified to MIL-PRF-19500/510 Class S. Commercial versions lack radiation testing, thermal cycling validation, and long-term life testing - making JANS1N5822 the only version approved for flight hardware where failure modes must be fully characterized and eliminated.
