8EWS08STR

Single Diodes Overview

The Vishay General Semiconductor - Diodes Division 8EWS08STR is a surface mountable input rectifier diode from the SAFEIR series, housed in a TO-252AA (D-Pak) package. It features an 800V maximum repetitive peak reverse voltage and supports an average forward current of 8A at a case temperature of 95°C. The device exhibits a low forward voltage drop of less than 1V at 5A and offers high surge capability with a non-repetitive peak surge current of 200A. Designed for reliable operation up to a junction temperature of 150°C, it utilizes glass passivation technology.

Single Diodes Feature Summary

• Optimized for very low forward voltage drop with moderate leakage characteristics
• Utilizes glass passivation technology for reliable operation up to 150°C junction temperature
• Provides outstanding voltage surge capability suitable for primary rectification stages

Single Diodes Applications

• Input rectification in power supply circuits
• Single-phase bridge rectifier configurations
• Three-phase bridge rectifier configurations

Single Diodes Procurement Notes

Verify that the ordering suffix STR corresponds to the specific tape and reel orientation required for your automated assembly line. Confirm the exact voltage code matches the 800V rating, as higher voltage variants exist within the same series family. Ensure compatibility with International Rectifier switches and output rectifiers sharing identical package outlines if used in integrated designs.

Single Diodes Selection Notes

Select this component when designing input stages requiring high voltage surge withstand capability alongside low conduction losses. The D-Pak package facilitates efficient thermal management through direct PCB mounting. Consider the derating curves for average forward current based on the expected case temperature and conduction angle of the specific application waveform.

Single Diodes Part Context

This part belongs to the SAFEIR series of surface mountable rectifiers designed for general-purpose input rectification. The series includes variants with different voltage ratings ranging from 800V to 1600V. These devices are engineered to complement International Rectifier switching components, ensuring mechanical and electrical consistency across power conversion modules.

Single Diodes Replacement Considerations

Consult factory documentation for higher voltage options up to 1600V. Verify pinout compatibility with existing TO-252AA footprints before substituting other single diode packages.
