8ETU04

Overview

The VS-8ETU04PBF is a fast recovery rectifier from the Vishay FRED Pt series, housed in a TO-220-2 through-hole package. It features a 400 V reverse voltage rating and an 8 A average forward current capability. The device exhibits a 60 ns reverse recovery time and a maximum forward voltage of 1.3 V at rated current. Operating temperatures range from -65°C to +175°C junction temperature.

Feature Summary

• Utilizes FRED Pt technology for optimized switching performance
• Designed for high thermal stability with extended operating temperature range
• Provides low reverse leakage current characteristics

Applications

• High-frequency power supply circuits
• Free-wheeling diode applications in inductive loads
• Snubber circuits requiring fast recovery characteristics

Procurement Notes

Verify component authenticity against official Vishay datasheets due to discontinued status. Confirm RoHS compliance markings on legacy inventory. Cross-reference manufacturer part numbers with authorized distributors to ensure traceability and quality assurance before integration into production systems.

Selection Notes

Select this component for designs requiring robust fast recovery performance in through-hole configurations. Ensure circuit parameters remain within the specified 400 V and 8 A limits. Consider thermal management requirements given the 175°C maximum junction temperature rating for reliable long-term operation.

Part Context

This rectifier belongs to the VS-8ET family utilizing FRED Pt silicon planar technology. The product line emphasizes reliability in high-speed switching environments. The TO-220-2 package provides mechanical stability and efficient heat dissipation for industrial-grade electronic assemblies.

Replacement Considerations

The MUR840G from onsemi is documented as a parameter-equivalent substitute. Verify pinout compatibility and thermal specifications when transitioning between manufacturers.
