8ETH03-1

Overview

The Vishay 8ETH03-1 is a hyperfast recovery rectifier utilizing FRED Pt technology, housed in a TO-262 (D2PAK) package. It features a 300 V repetitive peak reverse voltage and an 8 A average rectified forward current rating. The device exhibits a maximum reverse recovery time of 35 ns at 25 °C junction temperature. Electrical specifications include a typical forward voltage drop of 1.0 V at 8 A and a maximum reverse leakage current of 20 µA at rated voltage. The component supports an operating junction and storage temperature range from -65 °C to +175 °C.

Feature Summary

• Hyperfast recovery characteristics with optimized stored charge to minimize switching losses
• Planar structure with platinum doped lifetime control for ruggedness and reliability
• Low forward voltage drop and low leakage current performance
• Qualified for industrial level applications

Applications

• Output rectification stage of 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 official documentation to confirm package type and packaging format. The base part number indicates a TO-262 case style; ensure the suffix matches the required mechanical footprint. Confirm RoHS compliance status and lead-free designation if applicable to the assembly process. Cross-reference the document revision date to ensure the latest electrical parameters are utilized for design validation.

Selection Notes

Select this component for circuits requiring fast switching speeds and high thermal stability. The 300 V rating suits medium-voltage DC bus applications. Ensure the thermal management design accounts for the junction-to-case thermal resistance of 2.5 °C/W per leg. Verify that the peak surge current capability of 100 A meets the circuit's transient requirements. Consider the 175 °C maximum junction temperature for high-temperature environments.

Part Context

This device belongs to the 8ETH series of hyperfast rectifiers from Vishay High Power Products. It shares the same electrical characteristics as the 8ETH03S variant but differs in the physical package configuration. The series utilizes FRED Pt technology to achieve superior performance compared to standard recovery diodes. The TO-262 package provides robust mounting capabilities for power electronics applications.

Replacement Considerations

Public confirmed substitute part numbers: BYV29G-600,127 (WeEn Semiconductors), STTH8R06D (STMicroelectronics). Verify pinout compatibility and thermal resistance values before substitution.
