VS-20ETF08-M3

Single Diodes Overview

The VS-20ETF08-M3 is a fast soft recovery rectifier diode from Vishay Semiconductors, housed in a TO-220AC 2L package. It features an 800 V maximum repetitive peak reverse voltage and supports a 20 A average forward current at a case temperature of 113 °C. The device exhibits a low forward voltage drop of 1.31 V at 20 A and a typical reverse recovery time of 95 ns. It withstands a non-repetitive surge current of up to 320 A and operates within a junction temperature range of -40 °C to +150 °C.

Single Diodes Feature Summary

• Glass passivated pellet chip junction for stable operation under severe temperature and power cycling conditions
• Optimized design combining short reverse recovery time with low forward voltage drop
• Designed and qualified according to JEDEC-JESD 47 standards

Single Diodes Applications

• Output rectification and freewheeling in inverters, choppers, and converters
• Input rectification requiring strict adherence to conducted EMI restrictions

Single Diodes Procurement Notes

Verify the specific part number against official Vishay documentation to confirm electrical ratings and package dimensions. Ensure that thermal management designs account for the specified junction-to-case thermal resistance. Confirm compliance requirements such as RoHS and halogen-free status match project specifications before finalizing procurement.

Single Diodes Selection Notes

Select this component when high-frequency switching applications demand minimized reverse recovery losses alongside robust current handling capabilities. Evaluate the thermal environment carefully, as the 20 A rating is dependent on maintaining the case temperature at or below 113 °C. Consider the snap factor characteristics when designing snubber circuits to manage reverse recovery behavior effectively.

Single Diodes Part Context

This device belongs to the VS-20ETF...-M3 series of fast soft recovery rectifiers manufactured by Vishay Semiconductors. The series includes variants with different voltage ratings, specifically 800 V, 1000 V, and 1200 V options. All members share the same 20 A current rating and utilize the TO-220AC 2L through-hole package for mounting.

Single Diodes Replacement Considerations

Direct substitutes within the same series include VS-20ETF10-M3 (1000 V) and VS-20ETF12-M3 (1200 V). These alternatives maintain identical current ratings and package styles but offer higher voltage blocking capabilities.
