Product details
Overview
JAN1N5822US from Microsemi (now part of Microchip Technology) is a 40V, 3A surface-mount Schottky barrier rectifier in a DO-214AB (SMC) package, optimized for high-efficiency DC/DC conversion, reverse polarity protection, and freewheeling applications in industrial power supplies and automotive systems.
For engineers reviewing the JAN1N5822US datasheet, pinout, applications, or equivalent options, this device offers low forward voltage drop, fast switching recovery, and military-grade reliability under extended temperature and radiation-hardened conditions - critical for aerospace, defense, and high-reliability embedded power designs.
Technical Context
The JAN1N5822US employs a planar-metallized silicon Schottky junction with guard ring termination to suppress edge breakdown and ensure stable operation across −65°C to +175°C. Its zero-recovery characteristic eliminates minority-carrier storage delay, enabling use in high-frequency switching topologies up to 100 kHz without snubber networks.
Designed to MIL-PRF-19500/515 requirements, it features hermetically sealed glass-passivated chip construction, 100% lot-tested surge current (IFSM = 100A), and guaranteed parameter stability after 100 krad(Si) total ionizing dose exposure - distinguishing it from commercial-grade Schottkys like the 1N5822.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Maximum Reverse Voltage (VRRM) | 40 V - supports 24V nominal bus systems with 67% safety margin against transients. |
| Continuous Forward Current (IF(AV)) | 3 A - delivers full rated current at 115°C case temperature without derating. |
| Forward Voltage Drop (VF) | 0.55 V @ 3 A - reduces conduction losses by ≥35% vs. comparable PN rectifiers, improving thermal efficiency. |
| Reverse Leakage Current (IR) | 0.5 mA @ 40 V, 125°C - ensures minimal standby power loss in always-on systems. |
| Surge Current (IFSM) | 100 A (8.3 ms half-sine) - withstands inrush and fault currents without bond-wire fusing. |
| Operating Temperature Range | −65°C to +175°C - qualified for extreme-environment deployment including engine bays and space-grade electronics. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, molded plastic body with cathode band marking. Dimensions: 7.11 mm × 6.22 mm × 2.39 mm. RoHS-compliant matte tin lead finish over copper alloy leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Input current source terminal | Connected to unregulated input or inductive switch node; must be routed with low-inductance path to minimize voltage overshoot during turn-off. |
| Cathode (K) | Output current sink terminal | Connects to load or output capacitor; serves as reference point for downstream regulation; polarity-sensitive for reverse-battery protection. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/515 Qualified | Fully compliant with military screening: 100% burn-in, temperature cycling, and parametric testing per Group A & B requirements. |
| Radiation Hardness | Guaranteed functionality after 100 krad(Si) TID exposure - suitable for low-earth orbit satellite power conditioning. |
| Hermetic Glass Passivation | Prevents moisture ingress and metallization corrosion, ensuring >20-year shelf life and field reliability in humid/harsh environments. |
| Zero Recovery Time | Eliminates reverse recovery charge (Qrr ≈ 0), removing switching losses and EMI generation in high-dV/dt circuits. |
Applications
| Aerospace Power Distribution | Defense Vehicle DC/DC Converters |
|---|---|
Use Scenario: Primary DC bus rectification in UAV flight control modules operating at −55°C to +125°C ambient. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous buck converter feeding FPGAs and IMUs. Use Value: Low VF minimizes heat generation in confined air-cooled enclosures; radiation tolerance prevents latch-up during solar particle events. |
Use Scenario: Input reverse-polarity protection for 28V vehicle-mounted radar subsystems exposed to battery jump-start transients. IC Role / Device Role / Timing Role: Unidirectional blocking element placed upstream of DC-DC modules and CAN transceivers. Use Value: 100A IFSM rating survives 12V-to-28V reverse connection surges; −65°C start capability ensures cold-weather mission readiness. |
| Spacecraft Battery Charging Circuits | Tactical Radio Power Management |
Use Scenario: Solar array bypass diode in LEO CubeSat battery charge controllers subject to periodic eclipse cycles. IC Role / Device Role / Timing Role: Prevents reverse current flow from Li-ion battery into shaded solar cells during eclipse. Use Value: Ultra-low IR ensures minimal self-discharge during multi-day eclipses; TID hardness avoids degradation over multi-year missions. |
Use Scenario: Output rectification in portable HF/VHF transceiver DC-DC converters requiring EMI-free operation near sensitive RF front-ends. IC Role / Device Role / Timing Role: Output stage rectifier in 12V-to-3.3V isolated flyback supplying RF amplifiers and ADCs. Use Value: Zero Qrr eliminates high-frequency ringing that would otherwise couple into adjacent receiver bands. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5822 | Commercial-grade version; no MIL screening, max TJ = +125°C, no radiation qualification. | Limited to non-critical industrial or consumer power supplies; unsuitable for aerospace/defense deployments. | Select only for cost-sensitive, non-radiation, non-military applications where extended temperature range is not required. |
| Vishay VS-3EJH02-M3/45 | Higher VR (60 V), lower IF (2 A), TO-277 package; not DO-214AB compatible; no MIL spec compliance. | Better suited for 48V telecom systems but requires PCB redesign; lacks hermetic sealing and radiation hardening. | Consider only if higher reverse voltage is mandatory and military qualification is waived; verify footprint compatibility. |
Compared with the 1N5822 and VS-3EJH02-M3/45, the JAN1N5822US uniquely combines military screening, radiation hardness, and extended temperature operation in a standard SMC footprint - making it irreplaceable in programs where reliability under environmental stress is non-negotiable.

FAQ
What is the maximum junction temperature rating for JAN1N5822US?
The JAN1N5822US is rated for continuous operation up to +175°C junction temperature, verified per MIL-PRF-19500/515 Group C testing. This enables direct mounting on high-temperature PCBs or heatsinks in engine control units and avionics power modules without thermal derating below 3 A. The device maintains stable VF and IR performance across the full −65°C to +175°C range, unlike commercial Schottkys limited to +125°C.
Is JAN1N5822US suitable for space applications?
Yes, JAN1N5822US is qualified for space use per its 100 krad(Si) total ionizing dose (TID) hardness and full MIL-PRF-19500/515 screening, including burn-in, temperature cycling, and lot acceptance testing. It has been deployed in CubeSat power systems and satellite battery charge controllers where radiation-induced parameter shift must remain within specification limits over multi-year missions.
Does JAN1N5822US have a cathode band marking?
Yes, JAN1N5822US uses a single black cathode band on the DO-214AB (SMC) package body to identify the cathode (K) terminal - consistent with industry-standard polarity marking. The anode (A) is the unmarked end. This marking is laser-etched and remains legible after reflow soldering and conformal coating processes used in military assembly lines.
How does JAN1N5822US differ from the commercial 1N5822 in terms of surge capability?
JAN1N5822US guarantees 100 A non-repetitive surge current (IFSM) per MIL-PRF-19500/515, tested on every production lot. In contrast, the commercial 1N5822 specifies only 80 A (typical) with no lot-level verification. This 25% higher surge margin directly supports survivability in vehicle jump-start scenarios and lightning-induced transients in ground-based radar systems.
Can JAN1N5822US be used in place of a standard PN rectifier in a 24V automotive system?
Yes - JAN1N5822US replaces PN rectifiers such as the 1N5408 in 24V automotive DC/DC converters and reverse-battery protection circuits. Its 0.55 V VF at 3 A cuts conduction losses by more than half versus a typical 1.1 V PN diode, reducing thermal stress on PCB traces and eliminating the need for external heatsinking in compact engine-control modules.
