Procurement Notes

Verify the specific suffix

Selection Notes

Select this component when designing circuits requiring fast recovery times below 100 ns and moderate current handling up to 14 A. Ensure the TO-220AC package fits the thermal and mechanical constraints of the target PCB layout. Confirm that the 500 V reverse voltage rating exceeds the peak inverse voltage present in the application circuit under all operating conditions.

Part Context

This part belongs to the BYT79 series of ultrafast rectifiers from WeEn Semiconductors. The series is designed for general-purpose high-speed rectification applications where standard recovery diodes are insufficient. The BYT79-500 variant specifically targets 500 V blocking requirements, complementing other voltage ratings in the family such as the 600 V version.

Replacement Considerations

Cross-reference with BYT79-600,127 for higher voltage tolerance. Verify pinout compatibility with TO-220AC packages before substitution.
