Overview
The Vishay VS-8EWF04STRL-M3 is a surface mountable fast soft recovery rectifier in the IR Series, housed in a TO-252AA (D-Pak) package. It features an average forward current of 8 A and a maximum repetitive peak reverse voltage of 400 V. The device exhibits a low forward voltage drop of 1.2 V at 8 A and a reverse recovery time of 55 ns. It supports a peak non-repetitive surge current of up to 170 A and operates within a junction temperature range of -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 reliable operation under severe temperature and power cycling conditions
Applications
- Output rectification and freewheeling diode in inverters, choppers, and converters
- Input rectifications requiring strict limitations on conducted EMI
Procurement Notes
Verify the specific ordering suffix 'TRL' indicates left orientation reel packaging when sourcing. Confirm that the part number prefix includes 'VS-' and the suffix '-M3' for lead-free compliance as per Vishay's standard nomenclature. Ensure the component matches the original International Rectifier specifications now managed by Vishay General Semiconductor.
Selection Notes
Select this component for applications requiring high-speed switching with minimal reverse recovery charge. The TO-252AA package provides efficient thermal dissipation suitable for power densities exceeding those of smaller packages. Consider the 400 V rating for medium-voltage DC link or AC input rectification stages where low conduction losses are critical.
Part Context
This part belongs to the 8EWF..S series of fast soft recovery rectifiers originally developed by International Rectifier and acquired by Vishay. The series covers voltage ratings from 200 V to 600 V, all sharing similar electrical characteristics and the D-Pak surface mount form factor designed for robust performance in power electronics.
Replacement Considerations
Direct substitutes include other Vishay parts in the same series such as VS-8EWF04S-M3 (tube packaging) or VS-8EWF04STRR-M3 (right orientation reel). Cross-brand replacements must match the 8 A current, 400 V rating, and TO-252AA footprint while verifying equivalent reverse recovery times.
