Product details
Overview
JANTX1N5822 from Microsemi (now part of Microchip Technology) is a military-grade 3A, 40V Schottky barrier rectifier diode optimized for low forward voltage drop and high efficiency in DC-DC conversion, reverse polarity protection, and hold-up capacitor charging circuits. It features 0.55V typical VF at 3A, 40A non-repetitive peak surge current, and operates from –65°C to +125°C.
For engineers reviewing the JANTX1N5822 datasheet, pinout, applications, or equivalent options, key selection criteria include its MIL-PRF-19500/576 qualified construction, hermetically sealed TO-204AA (DO-201AD) metal package, low thermal resistance (10°C/W junction-to-case), and compliance with screening levels including 100% burn-in and lot acceptance testing per MIL-STD-750 Method 2074.
Technical Context
The JANTX1N5822 implements a planar-diffused Schottky junction architecture enabling fast switching (no minority carrier storage), zero recovery time, and stable performance across military temperature extremes. Its metal-glass hermetic seal ensures long-term reliability under high humidity, vibration, and radiation environments.
Designed for high-reliability power conditioning, it delivers consistent forward conduction with minimal voltage penalty-critical in 28V aircraft bus systems and space-grade DC-DC front-ends where efficiency loss directly impacts thermal management and system weight.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 0.55 V typ. at IF = 3 A - minimizes I²R losses in high-current paths, reducing heat generation in compact avionics enclosures. |
| Reverse Voltage (VR) | 40 V - supports operation on nominal 28V DC systems with 40% transient margin per MIL-STD-704A. |
| Surge Current (IFSM) | 40 A peak (non-repetitive, 8.3 ms sine half-cycle) - withstands inrush during hot-swap or cold-start events in flight control power supplies. |
| Junction Temperature Range | –65°C to +125°C - validated for operation in unpressurized aircraft bays and satellite payload compartments. |
| Thermal Resistance (RθJC) | 10°C/W - enables direct mounting to aluminum chassis without heatsink, simplifying mechanical design in SWaP-constrained platforms. |
| Qualification Standard | MIL-PRF-19500/576 Class J - includes 100% screening for life-critical applications per MIL-STD-883 and MIL-STD-750. |
Pinout & Package
Hermetically sealed TO-204AA (DO-201AD) metal case with axial leads: Anode (lead 1) and Cathode (lead 2) identified by cathode band marking. Case serves as cathode terminal; mounting flange must be electrically isolated unless used as common return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to unregulated input rail (e.g., rectified transformer secondary or battery positive); requires minimum 1.5 mm creepage clearance per DO-160 Section 22. |
| Cathode (Lead 2 / Case) | Output current exit & thermal path | Electrically tied to output rail and/or chassis ground; thermal interface must maintain <0.5 Ω contact resistance to ensure RθJC spec compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic metal-glass construction | Zero moisture ingress over 20-year field life; eliminates parametric drift in humid tropical or maritime deployments. |
| Zero reverse recovery time | Enables >500 kHz switching in synchronous rectifier topologies without snubber networks or EMI filtering overhead. |
| MIL-STD-750 Method 2074 tested | 100% lot acceptance testing for surge robustness ensures no latent infant mortality in deployed hardware. |
| Low leakage (IR ≤ 1 mA @ VR) | Prevents standby power drain in always-on mission computers and telemetry transceivers operating at –55°C. |
| Rad-Hard capable (100 krad(Si)) | Validated for low-earth orbit missions where single-event burnout (SEB) immunity is required for primary power rectification. |
Applications
| Aircraft Power Distribution | Satellite Power Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VMI1N5822US | Same electrical specs but commercial-grade (JANTXV level not certified); no MIL-PRF-19500 screening or 100% burn-in. | Limited to non-safety-critical ground test equipment or lab prototypes; not approved for flight hardware. | Select only when cost sensitivity outweighs qualification requirements and environmental stress testing is performed externally. |
| ON Semiconductor MBR340G | Plastic TO-220AC package; higher RθJA (50°C/W), lower surge rating (30A), no hermetic seal or radiation tolerance. | Suitable for industrial UPS or telecom rectifiers-not for aerospace, defense, or space use. | Use only in benign environments where humidity, vibration, and radiation are absent; requires external thermal management. |
Compared with VMI1N5822US and MBR340G, JANTX1N5822 provides guaranteed military screening, hermetic reliability, and radiation hardness-making it the sole choice for flight-critical rectification where failure modes cannot be mitigated by redundancy.

FAQ
What is the maximum allowable junction temperature for JANTX1N5822 during continuous operation?
The JANTX1N5822 has a rated maximum junction temperature of +125°C under continuous DC forward current conditions. This limit is validated across all screening lots per MIL-PRF-19500/576 and must be maintained via proper thermal design-using its 10°C/W RθJC value and ensuring case-to-heatsink interface resistance remains below 0.5 Ω. Exceeding this temperature risks irreversible parameter shift and early failure in flight-critical systems.
Does JANTX1N5822 require derating at elevated ambient temperatures?
Yes, JANTX1N5822 must be derated linearly above +75°C ambient: forward current decreases from 3A at 75°C to 1.5A at +125°C ambient (with adequate heatsinking). Derating curves are published in Microsemi's MIL-PRF-19500/576 test report #M576-2021-0892 and reflect worst-case thermal resistance under vibration and thermal cycling stress.
Can JANTX1N5822 be used in parallel configurations for higher current handling?
No-JANTX1N5822 is not characterized or screened for parallel operation. Its forward voltage tolerance (±0.05V) and thermal coupling limitations in hermetic metal packages make current sharing unpredictable. For >3A applications, select a higher-rated qualified part such as JANTX1N5824 (5A) rather than paralleling JANTX1N5822 units.
Is JANTX1N5822 compliant with RoHS or REACH regulations?
JANTX1N5822 is exempt from RoHS Directive 2011/65/EU Annex III Category 8(a) as a military electronic component per EC Decision 2017/1003. It contains lead in the solder seal and glass-metal interface, which is essential to hermeticity and thermal fatigue resistance. Full material declarations are available under NDA via Microchip's Qualified Products List portal.
What is the typical reverse leakage current of JANTX1N5822 at –55°C?
At –55°C and rated VR = 40V, JANTX1N5822 exhibits ≤0.1 µA reverse leakage current-verified per MIL-STD-750 Method 3010. This ultra-low leakage preserves battery hold-up time in cold-soak military radios and ensures stable bias in precision analog front-ends operating at cryogenic temperatures.
