8EWF12S

Overview

The Vishay 8EWF12S 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 peak repetitive reverse voltage of 1200 V. The device exhibits a low forward voltage drop of 1.3 V at 8 A and a reverse recovery time of 80 ns under specified conditions. It 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 under severe temperature and power cycling conditions.

Applications

Output rectification in inverters, choppers, and converters.
Freewheeling diode applications in power conversion circuits.
Input rectification requiring strict adherence to conducted EMI restrictions.

Procurement Notes

Verify the specific ordering suffix to confirm tape and reel orientation, as options include left or right orientation reels. Confirm that the component meets RoHS compliance standards if required by your manufacturing process. Ensure the selected variant matches the required voltage rating within the series specifications.

Selection Notes

Select this component for high-voltage applications requiring fast switching characteristics. The D-Pak package facilitates efficient thermal management through direct PCB mounting. Consider the 1200 V rating for systems operating near this threshold. Evaluate the 8 A current capacity against peak load requirements to ensure adequate performance margins.

Part Context

This part belongs to the 8EWF..S fast soft recovery rectifier series manufactured by Vishay General Semiconductor - Diodes Division. The series includes variants with different voltage ratings, such as 1000 V and 1200 V, all sharing similar electrical characteristics and packaging. The product was originally developed by International Rectifier before being acquired by Vishay.
