VS-8EWS08SPBF

Single Diodes Overview

The Vishay VS-8EWS08SPBF is a high voltage surface mount input rectifier diode rated for 8 A average forward current and 800 V maximum peak reverse voltage. It utilizes glass passivated pellet chip junction technology to ensure reliable operation up to a 150 °C junction temperature. The device features a low forward voltage drop of 1.1 V at 8 A and supports a non-repetitive surge current of 150 A. Packaged in a TO-252AA (D-PAK) outline, it is designed for primary rectification with outstanding voltage surge capability.

Single Diodes Procurement Notes

Verify the specific part number against official Vishay documentation to confirm the 800 V rating and D-PAK package configuration. Ensure compliance with RoHS3 lead-free specifications and MSL level 1 requirements during procurement. Cross-reference datasheet revision 16-Jan-17 for accurate thermal and electrical parameters before finalizing orders.

Single Diodes Selection Notes

Select this component when designing circuits requiring an 8 A single-diode rectifier with an 800 V blocking capability. The TO-252AA package provides a balance of thermal performance and surface-mount convenience. Evaluate the 1.1 V forward voltage drop against system efficiency targets and verify that the 150 A surge rating meets transient protection requirements.

Single Diodes Part Context

This component belongs to the 8EWS..SPbF series of high voltage surface mount input rectifiers from Vishay Semiconductors. The series includes variants with different voltage ratings, such as the 1200 V version. These devices are engineered for robust performance in demanding power conversion applications where high reliability and efficient heat dissipation are critical design factors.

Single Diodes Replacement Considerations
