8EWF02S

Single Diodes Overview

The Vishay 8EWF02S is a surface-mountable fast soft recovery rectifier in the IR Series, housed in a TO-252AA (D-Pak) package. It features a maximum average forward current of 8 A and a repetitive peak reverse voltage of 200 V. The device exhibits a low forward voltage drop of 1.2 V at 8 A and a reverse recovery time of 55 ns. Designed for robust performance, it includes glass passivation for stability under severe temperature and power cycling conditions.

Single Diodes Feature Summary

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

Single Diodes Applications

• Output rectification and freewheeling diode in inverters, choppers and converters
• Input rectifications where severe restrictions on conducted EMI should be met

Single Diodes Procurement Notes

Verify the specific part number against the manufacturer's datasheet to confirm electrical ratings and package type. Ensure compatibility with the intended thermal management requirements, as the junction-to-ambient resistance varies significantly based on PCB copper area. Confirm that the application environment stays within the specified operating temperature range of -40°C to 150°C.

Single Diodes Selection Notes

Select this component when a fast soft recovery characteristic is required to minimize switching losses and electromagnetic interference. The 8A current rating and 200V blocking voltage define its operational limits. Consider the TO-252AA package for surface mount applications requiring efficient heat dissipation through the exposed pad.

Single Diodes Part Context

The 8EWF02S belongs to the 8EWF..S series of fast soft recovery rectifiers from Vishay General Semiconductor - Diodes Division. This series was originally developed by International Rectifier before being acquired by Vishay. The '02' code specifically denotes the 200V voltage rating variant within the broader family that also includes 400V and 600V options.

Single Diodes Replacement Considerations

Check for 8EWF04S or 8EWF06S if higher voltage ratings are needed while maintaining the same current and package specifications. Verify pinout compatibility with the TO-252AA footprint before substitution.
