8ETH03S

Overview

The Vishay 8ETH03S is a hyperfast rectifier featuring FRED Pt technology, housed in a D2PAK (TO-263AB) package. It supports a repetitive peak reverse voltage of 300 V and an average forward current of 8 A at 155 °C case temperature. The device exhibits a maximum reverse recovery time of 35 ns and a typical junction capacitance of 31 pF. Operating temperatures range from -65 °C to 175 °C.

Feature Summary

• Hyperfast recovery characteristics with optimized stored charge
• Platinum-doped lifetime control for ruggedness
• Low forward voltage drop efficiency
• Industrial level qualification

Applications

• Output rectification in SMPS
• UPS systems
• DC-to-DC converters
• Freewheeling diodes in low voltage inverters
• Chopper motor drives

Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel orientation. Confirm lead-free status and check for any discontinued variants within the same series before finalizing procurement plans.

Selection Notes

Select this component for high-frequency switching applications requiring minimal reverse recovery losses. Ensure thermal management accounts for the specified junction-to-case resistance and operating temperature limits.

Part Context

This part belongs to the 8ETH03 series of hyperfast rectifiers from Vishay High Power Products. It shares specifications with the 8ETH03-1 variant, differing primarily in the physical package style, which is TO-262AA for the -1 suffix.

Replacement Considerations

The 8ETH03-1 serves as a direct functional substitute, utilizing the TO-262AA package instead of the D2PAK form factor while maintaining identical electrical ratings.

FAQ
