Overview
The Vishay VS-8EWF04STRR-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. Maximum surge current ratings are 170 A with rated voltage reapplied and 200 A without voltage reapplied. Operating junction temperature ranges 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 under severe temperature and power cycling conditions.
Applications
- Output rectification and freewheeling diode in inverters, choppers, and converters.
- Input rectifications requiring strict adherence to conducted EMI restrictions.
Procurement Notes
Verify the specific ordering suffix 'TRR' corresponds to the right orientation reel configuration as defined in the manufacturer's ordering information table. Confirm that the component carries the appropriate environmental compliance markings, such as the M3 designation for lead-free status, prior to final procurement integration.
Selection Notes
Select this component when designing circuits requiring fast soft recovery characteristics to minimize switching losses and electromagnetic interference. Ensure the thermal management strategy accommodates the specified junction-to-case thermal resistance for the intended conduction angles and ambient temperatures.
Part Context
This part belongs to the 8EWF..S series of fast soft recovery rectifiers originally developed by International Rectifier and subsequently acquired by Vishay Intertechnology, Inc. The series is designed for high-efficiency power conversion applications where rapid switching and low conduction losses are critical performance factors.
Replacement Considerations
Consult official cross-reference documentation for verified substitutes. Generic replacements must match the 400 V rating, 8 A current capacity, and TO-252AA package dimensions to ensure mechanical and electrical compatibility.
FAQ
What does the TRR suffix indicate for this component?
The TRR suffix indicates that the components are supplied in a tape and reel format with a right orientation.
How does glass passivation benefit this diode?
Glass passivation ensures stable and reliable operation even under the most severe temperature and power cycling conditions.
