1N3890AR

Single Diodes Overview

The Microchip Technology 1N3890AR is a fast recovery rectifier diode designed for high-reliability applications. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current rating of 20 A. The device exhibits a typical reverse recovery time of 150 ns and maintains a low reverse leakage current of 10 µA at its rated voltage. Constructed in a hermetically sealed DO-203AA (DO-4) package with stud mount terminals, it supports a junction temperature range from -65°C to 175°C.

Single Diodes Feature Summary

• Hermetically sealed construction ensures environmental protection and long-term reliability
• Fast recovery characteristics minimize switching losses in high-frequency circuits
• Military qualification per MIL-PRF-19500/304 guarantees performance under extreme conditions

Single Diodes Applications

Single Diodes Procurement Notes

Verify the specific suffix 'AR' against the manufacturer's official datasheet to confirm the exact packaging configuration and lot traceability requirements. Ensure that the procurement channel provides valid documentation confirming compliance with MIL-PRF-19500/304 standards. Cross-reference the manufacturing date code to ensure compatibility with current assembly specifications.

Single Diodes Selection Notes

Select this component when a hermetically sealed, military-grade fast recovery rectifier is required for critical environments. The 100 V rating and 20 A current capacity define the operational limits. Consider the stud mount package for thermal management needs. Verify that the 150 ns reverse recovery time meets the specific circuit switching frequency requirements.

Single Diodes Part Context

This part belongs to the 1N3890 series of fast recovery rectifiers manufactured by Microchip Technology. The series includes variants such as 1N3890A and 1N3890R, which share similar electrical characteristics but may differ in packaging or qualification levels. The 1N3890AR specifically denotes the version qualified for space and high-reliability markets.

Single Diodes Replacement Considerations

Direct substitutes include other military-qualified fast recovery rectifiers in the DO-203AA package with equivalent 100 V and 20 A ratings. Verify that any replacement meets the same MIL-PRF-19500/304 standard and hermetic sealing requirements to maintain system integrity.
