1N3647A

Single Diodes Overview

The Microchip Technology 1N3647A is a high-voltage standard recovery rectifier diode qualified per MIL-PRF-19500/279. It features a voidless hermetically sealed glass package with tungsten slugs for thermal stability. The device supports a working peak reverse voltage of 10,000 V and a steady-state power dissipation of 1.5 W at 25°C. It operates within a junction temperature range of -65°C to +175°C and provides a minimum breakdown voltage of 3,600 V.

Single Diodes Procurement Notes

Verify the specific revision level and qualification status (JAN/JANTX) required for your application, as these levels apply only to certain part numbers in this series. Confirm RoHS compliance requirements, noting that compliant versions are available on commercial grade only. Ensure ordering specifications match the exact JEDEC type number and terminal finish options provided by the manufacturer.

Single Diodes Selection Notes

Select the 1N3647A when applications demand extreme reverse voltage blocking capabilities up to 10,000 V. Consider this component for environments requiring inherent radiation hardness and long-term thermal stability due to its voidless glass construction. Evaluate the 1.5 W power dissipation rating against your thermal management constraints at specified ambient temperatures.

Single Diodes Part Context

This component belongs to a series of high-voltage rectifiers designed for critical infrastructure and defense electronics. Manufactured by Microsemi (now Microchip Technology), it utilizes advanced glass sealing techniques to ensure reliability in harsh conditions. The series includes variants with different voltage ratings to suit diverse high-voltage rectification needs.

Single Diodes Replacement Considerations

Consult official cross-reference lists for equivalent parts from other manufacturers. Verify that any substitute meets the same MIL-PRF-19500/279 qualification and hermetic sealing requirements. Ensure electrical parameters such as breakdown voltage and surge current capability match or exceed original specifications.
