8ETH03

Overview

The Vishay 8ETH03 is a single hyperfast recovery rectifier from the FRED Pt series, rated for 300 V repetitive peak reverse voltage and 8 A average forward current. It features a maximum forward voltage drop of 1.25 V at 8 A and a typical reverse recovery time of 35 ns. The device operates within a junction temperature range of -65 °C to +175 °C and utilizes a TO-220AC package.

Feature Summary

• Hyperfast recovery characteristics with optimized stored charge
• Platinum-doped lifetime control for ruggedness
• Low leakage current performance
• Lead-free construction compliant with RoHS standards

Applications

• Output rectification in switch-mode power supplies (SMPS)
• Uninterruptible power supply (UPS) systems
• DC-to-DC converters
• Freewheeling diodes in low voltage inverters
• Chopper motor drives

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm compliance requirements and packaging details. Confirm that the component meets industrial level qualification standards required for the target application environment before finalizing procurement specifications.

Selection Notes

Select this component for circuits requiring fast switching speeds to minimize over dissipation in switching elements. Ensure thermal management accommodates the specified thermal resistance values. Validate electrical parameters against actual operating conditions rather than relying solely on datasheet typicals.

Part Context

This part belongs to the Vishay FRED Pt family of high-power hyperfast rectifiers. It is designed to provide superior overall performance compared to standard recovery devices. The planar structure ensures reliability and consistent electrical characteristics across the operating temperature range.

Replacement Considerations

Check for direct equivalents such as VS-8ETH03-M3 or VS-8ETH03-1PBF which share similar electrical ratings but may differ in package style or lead-free status.
