8ETH06-1

Overview

The Vishay 8ETH06-1 is a hyperfast recovery rectifier utilizing FRED Pt technology, housed in a TO-262 (I2PAK) through-hole package. It features an average forward current of 8 A and a maximum repetitive reverse voltage of 600 V. The device exhibits a typical reverse recovery time of 18 ns and a peak reverse recovery current of 2.4 A at 25 °C. Forward voltage drop is typically 2.0 V at 8 A, rising to 2.4 V maximum. Reverse leakage current is limited to 50 µA at rated voltage and 25 °C. Thermal resistance from junction to case is 1.42 °C/W, supporting operation up to 175 °C.

Feature Summary

• Hyperfast recovery characteristics with low stored charge for minimized switching losses
• Platinum-doped lifetime control ensuring high reliability and ruggedness
• Soft recovery behavior reducing electromagnetic interference and over-dissipation
• Planar structure designed for industrial level qualification

Applications

• Power Factor Correction (PFC) boost stages in AC-DC sections of Switching Mode Power Supplies (SMPS)
• Inverter circuits
• Freewheeling diode applications

Procurement Notes

Verify component authenticity against the official datasheet Document Number 93934. Confirm the TO-262 package marking matches the specified device code. Check for lead-free status if required by assembly specifications, noting that standard production may vary. Ensure thermal management design accounts for the 1.42 °C/W junction-to-case resistance to maintain junction temperature within the -65 °C to 175 °C operating range during high-current operation.

Selection Notes

Select this component for designs requiring fast switching speeds and low reverse recovery charge to enhance efficiency in high-frequency power conversion. The 8 A current rating and 600 V blocking capability suit medium-power industrial applications. Consider the TO-262 package for through-hole mounting requirements where robust mechanical connection is necessary. Evaluate thermal performance under worst-case duty cycles to ensure junction temperatures remain below the 175 °C limit.
