AU01AV1

Overview

The AU01AV1 is a fast recovery diode manufactured by Sanken Electric USA Inc. It features a maximum repetitive reverse voltage of 600 V and an average forward rectified current of 500 mA. The device exhibits a typical forward voltage of 1.7 V at 500 mA and a maximum reverse recovery time of 400 ns. Reverse leakage current is specified as 10 µA at 600 V. It utilizes an axial through-hole package with bare leads compliant with RoHS standards.

Feature Summary

• Fast recovery characteristics optimized for high-speed switching applications
• High thermal stability with a junction temperature range up to 150°C
• Lead-free construction ensuring compliance with environmental directives

Applications

• Secondary side rectifier in flyback converters
• Freewheeling diode in offline buck and buck-boost converters
• LLC converter output rectification

Procurement Notes

Verify the specific suffix AV1 against the manufacturer datasheet to confirm lead finish and marking variations. Confirm RoHS compliance status directly with the supplier. Ensure the axial package dimensions match the target PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a 600 V rating is required for primary or secondary rectification. The 400 ns reverse recovery time suits general-purpose high-frequency power supplies. Verify that the 500 mA current capacity meets the circuit load demands under all operating conditions.
