AS01WS

Overview

The AS01WS is a single standard rectifier diode manufactured by Sanken Electric USA Inc. It features a maximum DC reverse voltage (Vr) of 400 V and an average rectified forward current (Io) of 600 mA. The device utilizes an axial through-hole package and operates within a junction temperature range of -40°C to 150°C. Key electrical parameters include a maximum reverse leakage current of 10 µA at 600 V and a forward voltage drop of 1.7 V at 500 mA. The component is classified as a standard speed diode with a typical reverse recovery time of 400 ns.

Procurement Notes

Verify the specific suffix 'WS' against the manufacturer's official datasheet to confirm exact mechanical dimensions and marking codes, as suffixes often denote packaging or variant differences. Ensure the sourcing channel provides original manufacturer documentation to validate authenticity. Cross-reference the part number with authorized distributors to confirm current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a 400 V reverse voltage rating and 600 mA current capacity are required for through-hole applications. Consider the 400 ns reverse recovery time for compatibility with the target switching frequency. Verify that the axial package fits the PCB layout constraints and that the operating temperature range meets the environmental requirements of the end application.

Part Context

The AS01WS belongs to the AU/AS series of discrete semiconductors from Sanken Electric, which are widely used in power electronics. This series includes various rectifier diodes designed for efficiency and reliability in AC-DC conversion. The AS01WS specifically addresses needs for moderate voltage and current levels in compact axial packages, serving as a fundamental building block in consumer and industrial power supplies.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include AU01AV, AU01AV0, AU01AV1, AU01AWK, and AU01AWS. Verify that any replacement matches the 400 V Vr, 600 mA Io, and axial package specifications.
