1N6763

Overview

The Microchip Technology 1N6763 is a dual ultrafast power rectifier qualified under MIL-PRF-19500/642. It operates within a junction temperature range of -55°C to 175°C and utilizes a TO-254AA package for through-hole mounting. The device features a maximum DC reverse voltage of 150 V and an average rectified current of 12 A. Forward voltage is specified at 1.05 V when conducting 12 A, with a maximum reverse leakage current of 10 µA at 150 V. The unit exhibits a fast recovery characteristic with a reverse recovery time of 35 ns and a capacitance of 300 pF at 5 V and 1 MHz.

Feature Summary

• Dual ultrafast power rectification architecture
• Military qualification per MIL-PRF-19500/642 standard
• High thermal stability up to 175°C junction temperature

Applications

• High-reliability military electronic systems
• Ultrafast switching power supply circuits
• Industrial equipment requiring high surge current tolerance

Procurement Notes

Verify the specific revision level and lot traceability against the current MIL-PRF-19500/642 specification requirements before procurement. Ensure that the receiving inspection procedures account for the TO-254AA lead frame configuration. Confirm that the supplier provides full documentation of the manufacturing origin and compliance with all applicable environmental directives relevant to the intended deployment region.

Selection Notes

Select this component for applications demanding rapid switching speeds combined with high current handling capabilities in harsh environments. The 35 ns reverse recovery time distinguishes it from standard recovery alternatives. Evaluate the thermal management requirements carefully, as the 12 A rating necessitates adequate heat dissipation strategies to maintain junction temperatures within the specified operational limits during continuous conduction cycles.

Part Context

This device belongs to the 1N676x series of dual ultrafast power rectifiers manufactured by Microchip Technology. It shares the same physical package and general electrical characteristics with the 1N6762 and 1N6764 variants, which are also qualified under the same military specification. The series is designed to provide robust performance in critical power conversion applications where reliability and speed are paramount.

Replacement Considerations

The 1N6762 and 1N6764 are confirmed public substitutes within the same military qualification family.
