Overview
The 1N5814R is a military-qualified ultrafast recovery power rectifier diode manufactured by Microchip Technology. It features a reverse stud mount configuration in the DO-203AA (DO-4) package. Key electrical parameters include a maximum repetitive reverse voltage of 100V and a forward current rating of 20A. The device exhibits a fast reverse recovery time of 35ns and supports a peak non-repetitive surge current of 400A, ensuring robust performance in high-reliability applications.
Feature Summary
- Military qualified for high-reliability environments where failure is not tolerated
- Ultrafast recovery characteristics with 35ns reverse recovery time
- Reverse stud mount design for secure mechanical attachment
Applications
- High-reliability military electronic systems
- Fast switching power rectification circuits
- Industrial equipment requiring ruggedized components
Procurement Notes
Verify the manufacturer designation as Microchip Technology or its predecessor Microsemi Corporation to ensure authenticity. Confirm the specific suffix 'R' indicates the correct military qualification and packaging variant. Check lead times as standard availability may vary due to specialized manufacturing processes. Ensure compatibility with existing thermal management solutions for stud-mounted devices.
Selection Notes
Select this component when military-grade reliability and ultrafast recovery are required. The 100V rating suits low-voltage high-current applications. The stud mount requires appropriate heatsinking and mounting hardware. Compare against standard industrial rectifiers if military qualification is unnecessary to optimize cost.
Part Context
This part belongs to the 1N5814 series of ultrafast recovery rectifiers designed for demanding applications. It represents a legacy product line maintained for defense and aerospace sectors. The DO-203AA package provides a standardized footprint for screw-type mounting in power electronics assemblies.
Replacement Considerations
Direct substitutes must match the 100V/20A rating, 35ns recovery time, and stud mount form factor. Verify equivalent military qualification status if replacing in certified systems. Cross-reference with other manufacturers offering DO-203AA ultrafast rectifiers.
