1N5623

Overview

The Microchip Technology 1N5623 is a single fast recovery rectifier diode rated for 1000 V reverse voltage and 1 A average forward current. It features a maximum forward voltage of 1.6 V at 3 A, a peak surge current capacity of 25 A, and a reverse leakage current of 500 nA at 1000 V. The device exhibits a reverse recovery time of 500 ns and operates within a junction temperature range of -65°C to +175°C. It utilizes an axial leaded package configuration suitable for through-hole mounting.

Feature Summary

• Hermetically sealed voidless-glass construction with internal metallurgical bond
• Military qualification compliant with MIL-PRF-19500/429 standards
• Fast recovery performance optimized for high-reliability applications

Applications

• High-reliability aerospace systems
• Defense electronics requiring failure tolerance
• Industrial power conversion circuits

Procurement Notes

Verify the specific suffix (e.g., US/TR) against the datasheet to confirm package type and military qualification status. Confirm RoHS compliance requirements as standard versions may not meet these regulations. Validate that the axial leaded package matches the target PCB footprint and mounting constraints before finalizing procurement orders.

Selection Notes

Select this component when a 1000 V rating and 1 A current capacity are required in a hermetically sealed package. Ensure the design accommodates the 500 ns reverse recovery time and the wide operating temperature range. Verify that the through-hole mounting style aligns with the assembly process and mechanical stress requirements of the application environment.
