AU01AV0

Overview

The AU01AV0 is a standard 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 rating of 500 mA. The device exhibits a typical forward voltage drop of 1.7 V at the rated current and a maximum reverse recovery time of 400 ns. Reverse leakage current is specified at 10 µA when tested at 600 V. The component utilizes an axial through-hole package and operates within a junction temperature range of -40°C to 150°C.

Feature Summary

• Fast recovery characteristics optimized for high-speed switching applications
• High thermal stability with extended operating junction temperature range
• Low reverse leakage current ensuring efficient blocking performance

Applications

• Secondary side rectification in flyback converters
• Freewheeling diodes in offline buck and buck-boost converters
• General purpose rectification in power supply circuits

Procurement Notes

Verify the specific suffix AV0 against official manufacturer documentation to confirm exact marking and packaging variations. Ensure compatibility with existing circuit designs regarding thermal management and peak inverse voltage ratings. Cross-reference datasheet parameters for reverse recovery time and forward voltage to validate performance requirements for the intended application environment.

Selection Notes

Select this component for applications requiring robust fast recovery performance with moderate current handling capabilities. The 600 V rating provides sufficient margin for common AC line voltages. Consider the axial leaded package for manual assembly or through-hole PCB layouts where surface mount options are not feasible. Evaluate thermal dissipation needs based on the 500 mA continuous current rating.

Part Context

The AU01AV0 belongs to the AU01 series of fast recovery diodes from Sanken Electric. This series is engineered for efficiency in switch-mode power supplies. The part shares core electrical specifications with other variants in the family, differing primarily in manufacturing lot codes or minor packaging distinctions. It serves as a reliable solution for general-purpose rectification tasks in consumer and industrial electronics.

Replacement Considerations

Official parameter-equivalent substitutes include AU01A, AU01AV, AU01AV1, AU01AWK, and AU01AWS. Verify pinout compatibility and ensure substitute parts meet the same 600 V reverse voltage and 500 mA current requirements before implementation.
