8EWF12STR

Overview

The Vishay VS-8EWF12SLHM3 is a surface-mountable fast soft recovery rectifier in the 8EWF..S series, housed in a TO-252AA (DPAK) 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 operates within a junction temperature range of -40°C to 150°C and meets AEC-Q101 automotive qualification standards.

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
Designed for applications requiring severe restrictions on conducted EMI

Applications

Output rectification in inverters, choppers, and converters
Freewheeling diode applications in power conversion circuits
Input rectifications where strict conducted EMI limits must be met

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm tape and reel orientation and packaging quantity. Confirm that the component meets the required AEC-Q101 automotive grade specifications if intended for automotive use. Ensure thermal management designs account for the specified junction-to-case thermal resistance values provided in the datasheet.

Selection Notes

Select this component when high voltage blocking capability up to 1200 V is required alongside efficient switching characteristics. The TO-252AA package provides a balance between current handling capacity and compact surface mount footprint. Consider the 80 ns reverse recovery time for high-frequency applications where minimizing switching losses and EMI is critical.

Part Context

This part belongs to the 8EWF..S fast soft recovery rectifier series from Vishay General Semiconductor. The series was originally developed by International Rectifier before being acquired by Vishay. The '12' in the model number indicates a 1200 V rating, while 'S' denotes the surface mountable configuration in the D-Pak package.
