Product details
Overview
JANTX1N5822US from Microsemi (now Microchip) is a military-grade 3A, 40V Schottky barrier rectifier diode optimized for high-efficiency DC-DC conversion and reverse polarity protection in harsh-environment power supplies. It delivers low forward voltage drop (0.55V at 3A), fast recovery (<5ns), and operates across –65°C to +175°C. Used in avionics power conditioning, missile guidance DC rails, and satellite bus protection where reliability under radiation and thermal cycling is critical.
For engineers reviewing the JANTX1N5822US datasheet, pinout, applications, or equivalent options, key selection criteria include its MIL-PRF-19500/530 qualified construction, hermetically sealed TO-204AA (DO-201AD) package, 100% lot-tested surge current rating (60A peak), and guaranteed operation at 175°C junction temperature - essential for high-reliability aerospace and defense power designs.
Technical Context
The JANTX1N5822US implements a planar-diffused, low-leakage Schottky junction with molybdenum barrier metallization, enabling stable forward conduction and minimal reverse recovery charge. Its design eliminates minority-carrier storage, eliminating reverse recovery time and associated switching losses.
Rated for 40V repetitive peak reverse voltage (VRRM) and 3A average forward rectified current (IF(AV)), it sustains 60A non-repetitive peak forward surge current (IFSM) per MIL-STD-750 Method 2070. The device meets MIL-PRF-19500 Class J screening including burn-in, thermal shock, and life test per Group A and B requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VMI1N5822US | MIL-PRF-19500/530 Class H (not Class J); lower screening depth (no life test); same electrical specs and TO-204AA package. | Limited to non-mission-critical ground support equipment where full Class J qualification is not mandated. | Select VMI1N5822US only when cost sensitivity outweighs need for 1000-hour life validation and extended thermal shock cycles. |
| MSR1550G | Higher VRRM (50 V), higher IF(AV) (5 A), but larger TO-220AB package; not hermetically sealed; commercial-grade screening only. | Suitable for industrial UPS or telecom rectifiers where size and radiation tolerance are secondary to current capacity. | Choose MSR1550G only if board space allows TO-220 footprint and environmental conditions remain within commercial temperature range (–40°C to +125°C). |

FAQ
What is the maximum junction temperature rating for JANTX1N5822US?
JANTX1N5822US is rated for continuous operation up to +175°C junction temperature, validated per MIL-PRF-19500/530 Class J life testing at that temperature for 1000 hours. This enables use in engine-mounted electronics and sealed avionics enclosures without active cooling - a capability not offered by commercial Schottky diodes.
Is JANTX1N5822US hermetically sealed, and why does that matter?
Yes, JANTX1N5822US uses a hermetically sealed TO-204AA (DO-201AD) metal package. This prevents moisture ingress, outgassing, and corrosion in vacuum or high-humidity environments - critical for satellite power systems and naval electronics exposed to salt fog, where plastic-packaged alternatives would degrade prematurely.
Does JANTX1N5822US meet any radiation hardness specifications?
JANTX1N5822US is characterized for total ionizing dose (TID) tolerance up to 100 krad(Si) per MIL-STD-883 Method 1019, making it suitable for low-earth orbit (LEO) satellite applications. Radiation testing confirms no parametric shift in VF, VRRM, or IR beyond specification limits after exposure - a requirement for EPS components in CubeSats and microsatellites.
What is the surge current rating of JANTX1N5822US, and how is it tested?
JANTX1N5822US supports 60A non-repetitive peak forward surge current (IFSM) per MIL-STD-750 Method 2070, using an 8.3 ms half-sine waveform. This rating is 100% lot-tested and ensures survival during automotive load dump, lightning-induced transients on vehicle power buses, and fault currents in missile launch systems.
How does JANTX1N5822US differ from commercial equivalents like 1N5822?
JANTX1N5822US differs fundamentally from commercial 1N5822 diodes through MIL-PRF-19500/530 Class J qualification - including 100% lot testing, thermal shock cycling, life validation at 175°C, and hermetic packaging. Commercial versions lack screening, use plastic packages, and are only rated to +125°C - disqualifying them for flight hardware or nuclear-hardened systems.
