8EWF04S

Overview

The VS-8EWF04S-M3 is a surface mountable fast soft recovery rectifier diode from the IR Series, manufactured by Vishay Semiconductors. It utilizes glass passivation for stable operation under severe temperature and power cycling conditions. The component features a TO-252AA (D-Pak) package with an average forward current rating of 8 A at a case temperature of 96°C. Key electrical specifications include a maximum repetitive peak reverse voltage of 400 V, a maximum forward voltage drop of 1.2 V at 8 A, and a typical reverse recovery time of 55 ns. The device supports a junction temperature range from -40°C to +150°C.

Feature Summary

Optimized for combined short reverse recovery time, low forward voltage drop, and low leakage current.
Glass passivation ensures stable and reliable operation in severe temperature and power cycling conditions.

Applications

Output rectification and freewheeling diodes in inverters, choppers, and converters.
Input rectifications requiring strict adherence to conducted EMI restrictions.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging orientation and tape-and-reel specifications. Ensure that the requested part number matches the exact voltage code and series designation required for the application. Cross-reference the datasheet revision date to confirm the validity of the thermal and electrical parameters provided.

Selection Notes

Select this component when designing circuits that require fast soft recovery characteristics to minimize switching losses and electromagnetic interference. Consider the thermal resistance values and derating curves for average forward current based on the expected case temperature and conduction angle. Evaluate the surge current capabilities relative to the circuit's fault conditions and pulse duration requirements.

Part Context

This component belongs to the 8EWF..S fast soft recovery rectifier series, originally developed by International Rectifier and subsequently acquired by Vishay Intertechnology, Inc. The series is designed for high-performance power conversion applications where rapid switching and low conduction losses are critical. The product line includes various voltage ratings within the same package style.

Replacement Considerations

Consult the manufacturer's cross-reference data or equivalent product lists for verified substitute part numbers. Ensure any replacement maintains compatibility with the TO-252AA package dimensions and meets or exceeds the original electrical ratings.
