Product details

Overview

JANS1N5822US from Semtech is a JANS-qualified 40 V, 3 A surface-mount Schottky rectifier diode designed for high-reliability space applications including satellite power conditioning and launch vehicle DC-DC converters. It features low forward voltage (0.55 V at 3 A), fast recovery (<100 ns), and operates across –65°C to +125°C.

For engineers reviewing the JANS1N5822US datasheet, pinout, applications, or equivalent options, this page delivers verified military-grade specs, MIL-PRF-19500/620 compliance, surface-mount package dimensions, and space-qualified thermal and radiation performance data.

Technical Context

JANS1N5822US employs a platinum-silicide Schottky barrier structure with Category I eutectic die bonding and glass-sleeve passivation for enhanced mechanical robustness and radiation tolerance. Its unidirectional configuration supports half-wave rectification in primary and secondary power stages.

The device meets MIL-PRF-19500/620 requirements for Schottky diodes and is fully traceable to wafer lot, with single-diffusion processing, laser serialization, and guaranteed homogeneity - critical for mission-critical avionics and orbital systems requiring zero fallout risk.

Key Specifications

Parameter	Value and Actual Design Meaning
Forward Voltage	0.55 V at 3 A - enables high-efficiency power conversion with minimal conduction loss in compact space-grade SMPS.
Reverse Voltage (V_R)	40 V - rated for use in low-voltage bus regulation and battery charging circuits in LEO satellites.
Operating Temperature	–65°C to +125°C - qualified for cryogenic launch environments and sustained operation in thermally uncontrolled spacecraft bays.
Recovery Time	<100 ns - supports high-frequency switching (>100 kHz) without reverse recovery losses or EMI spikes.
Package Type	Surface-mount DO-214AC (SMA) - compatible with automated SMT assembly and meets MIL-STD-750 test method 2074 for solderability.
Qualification Standard	MIL-PRF-19500/620 - ensures full JANS screening including burn-in, temperature cycling, and radiation hardness assurance (RHA).

Pinout & Package

Package: DO-214AC (SMA), surface-mount, with OFHC copper terminations and hot-solder dip plating per MIL-PRF-19500 construction guidelines.

Pin/Terminal	Circuit Role	Design Meaning
Anode (A)	Current entry point during forward conduction	Connected to input side of rectifier stage; requires thermal relief pad for 3 A continuous current dissipation.
Cathode (K)	Current exit point during forward conduction	Connected to output filter capacitor or load; polarity marking on package body aligns with cathode band.

Key Features

Feature	Design Value
Low forward voltage drop	0.55 V @ 3 A reduces power loss by >40% vs. standard silicon rectifiers in 28 V bus systems.
Category I eutectic bond	Ensures die attachment integrity under mechanical shock (≥1000 g) and thermal cycling (–65°C/+125°C, 500 cycles).
Wafer-level traceability	Laser-marked serialization enables full lot pedigree tracking from wafer to finished device for NASA/GSFC mission audits.
Single diffusion lot processing	Eliminates parametric variation between devices within a batch - critical for redundant power rail matching.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-3EJH04-M3/45	40 V, 3 A, but only commercial AEC-Q101 qualified - no JANS screening or RHA data.	Approved for automotive ADAS ECUs; not cleared for flight hardware or radiation environments.	Select only for ground-test bench equivalents or non-flight qualification prototypes.
Microsemi (now Microchip) JANTXV1N5822US	Identical electrical specs and DO-214AC package; differs in wafer source and upscreening protocol per MIL-PRF-19500/620 Rev D.	Accepted in DoD missile guidance programs; has different lot traceability format and fallout summary reporting.	Interchangeable in existing designs if procurement logistics favor dual-source availability.

Compared with JANS1N5822US, VS-3EJH04-M3/45 lacks radiation assurance and JANS documentation, while JANTXV1N5822US offers identical performance with alternate qualification lineage - enabling supply chain diversification without redesign.

FAQ

What is the maximum junction temperature rating for JANS1N5822US?

JANS1N5822US is rated for a maximum junction temperature of +125°C under continuous operation. This limit is defined by its Schottky barrier metallization stability and Category I eutectic bond integrity, and must be maintained via proper PCB copper pour design and thermal vias - especially when delivering 3 A in confined space-grade enclosures.

Does JANS1N5822US meet MIL-PRF-19500/620 Rev G requirements?

Yes, JANS1N5822US complies with MIL-PRF-19500/620 Rev G for Schottky diodes, including full JANS screening: 168-hour burn-in, 500-cycle temperature cycling (–65°C/+125°C), and radiation hardness assurance testing per MIL-STD-883 TM1019. Documentation includes lot-specific fallout summaries and wafer traceability reports.

Is JANS1N5822US suitable for bidirectional current flow?

No, JANS1N5822US is a unidirectional Schottky rectifier. Its anode-to-cathode conduction path supports forward current only; reverse breakdown is limited to 40 V and not intended for controlled conduction. For bidirectional protection, discrete TVS or dedicated bridge configurations must be used alongside JANS1N5822US.

What is the typical forward voltage at 1 A for JANS1N5822US?

The typical forward voltage of JANS1N5822US at 1 A and +25°C is 0.47 V, measured per MIL-STD-750 Method 3011. At elevated temperatures (+125°C), V_F decreases to ~0.42 V due to Schottky barrier physics - a key advantage over silicon diodes in thermally demanding space applications.

Can JANS1N5822US be substituted with JANS1N5822 (axial version) in the same PCB layout?

No - JANS1N5822US uses DO-214AC (SMA) surface-mount packaging, while JANS1N5822 uses DO-41 axial leads. Their footprints, thermal paths, and assembly processes are incompatible. Substitution requires board redesign, requalification, and updated thermal modeling - JANS1N5822US is not a drop-in replacement for the axial variant.
