Overview
The Vishay 8EWS12STRL is a surface mountable input rectifier diode from the SAFEIR series, housed in a TO-252AA (D-Pak) package. It features a maximum repetitive peak reverse voltage of 1200V and an average forward current rating of 8A at a case temperature of 95°C. The device exhibits a low forward voltage drop of 1.0V at 5A and supports a peak one-cycle non-repetitive surge current of 200A. It operates within a junction temperature range of -55°C to 150°C and utilizes glass passivation technology for reliable performance.
Feature Summary
- Optimized for very low forward voltage drop with moderate leakage current
- Glass passivation technology ensures reliable operation up to 150°C junction temperature
- High reverse voltage capability provides outstanding voltage surge protection
- Designed for primary rectification in input stages
Applications
- Single-phase bridge rectification
- Three-phase bridge rectification
- Input stage primary rectification
Procurement Notes
Verify the specific ordering suffix 'TRL' indicates the left reel tape and reel option when placing orders. Confirm that the component is sourced from Vishay General Semiconductor - Diodes Division, as the datasheet references International Rectifier branding. Ensure compatibility with standard SMD/SMT assembly processes and verify compliance with RoHS directives if required by the application specifications.
Selection Notes
Select this component for applications requiring high voltage isolation and robust surge handling in a compact surface mount footprint. The 1200V rating suits high-voltage AC-DC conversion systems. Consider the thermal resistance characteristics and ensure adequate PCB copper area or heatsinking to maintain junction temperatures within the specified limits during continuous operation.
Part Context
The 8EWS12STRL belongs to the 8EWS..S SAFEIR series of surface mountable input rectifiers. This series is characterized by optimized forward voltage drops and high reverse voltage capabilities. The components are designed to complement International Rectifier switches and output rectifiers sharing identical package outlines, facilitating integrated power supply designs.
Replacement Considerations
Consult the manufacturer for alternative part numbers offering higher voltage ratings up to 1600V. Verify pinout compatibility and thermal performance metrics before substituting with other D-Pak rectifiers.
