Overview
The Vishay 8EWF02STR 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 200 V. The device exhibits a maximum forward voltage drop of 1.2 V at 8 A and a typical reverse recovery time of 55 ns. It supports a peak surge current of 170 A and operates within a junction temperature range of -40 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 limitations on conducted EMI.
Procurement Notes
Verify the specific suffix 'STR' against manufacturer documentation to confirm tape and reel orientation and packaging specifications. Ensure the component matches the required 200V rating and D-Pak footprint for your design. Cross-reference the datasheet revision date to confirm electrical characteristics have not been updated.
Selection Notes
Select this component when a fast soft recovery characteristic is required to minimize switching losses and electromagnetic interference. The TO-252AA package provides a balance between thermal performance and surface mount convenience. Verify that the 200V breakdown voltage aligns with the circuit's peak reverse voltage requirements.
Part Context
This part belongs to the 8EWF..S series of fast soft recovery rectifiers from Vishay General Semiconductor. The series includes variants with different voltage ratings, such as 400V and 600V options, all sharing similar current handling and package configurations. The product line was originally developed by International Rectifier before being acquired by Vishay.
Replacement Considerations
Consult official substitution lists for equivalent fast soft recovery diodes in the TO-252AA package. Verify that any replacement maintains the 8A current rating, 200V voltage rating, and compatible reverse recovery time specifications.
FAQ
What is the maximum repetitive peak reverse voltage for the 8EWF02S?
The maximum repetitive peak reverse voltage (VRRM) for the 8EWF02S variant is 200 V.
How does glass passivation benefit this component?
Glass passivation ensures stable and reliable operation in the most severe temperature and power cycling conditions.
