8EWS08STRR

Overview

The Vishay 8EWS08STRR is a surface mountable input rectifier diode from the SAFEIR series, housed in a TO-252AA (D-Pak) package. It features an 800 V maximum repetitive peak reverse voltage and supports an average forward current of 8 A at a case temperature of 95 °C. The device exhibits a low forward voltage drop of 1.0 V at 5 A and 1.1 V at 8 A. It withstands a peak non-repetitive surge current of 200 A for a 10 ms sine pulse with no voltage reapplied. Operating junction temperatures range from -55 °C to 150 °C.

Feature Summary

Optimized for very low forward voltage drop with moderate leakage characteristics
Glass passivation technology ensures reliable operation up to 150 °C junction temperature
High reverse voltage capability provides outstanding voltage surge performance

Applications

Input stage primary rectification
Single-phase bridge circuits
Three-phase bridge circuits

Procurement Notes

Verify the specific suffix STRR indicates right orientation reel packaging when ordering. Confirm that the component is sourced from Vishay General Semiconductor or authorized distributors to ensure authenticity. Check datasheet revision G for accurate thermal resistance values and footprint dimensions before finalizing PCB layout designs.

Selection Notes

Select this component for applications requiring high surge capability and low conduction losses in power supply inputs. Ensure the design accommodates the specified thermal resistance of 3 °C/W junction-to-case for adequate heat dissipation. Verify that the 800 V rating aligns with the system's peak reverse voltage requirements under all operating conditions.

Part Context

This part belongs to the 8EWS..S SAFEIR series of surface mountable rectifiers. The series includes variants with different voltage ratings such as 1000 V and 1200 V. These components are designed to be used alongside International Rectifier switches and output rectifiers sharing identical package outlines.
