VS-20ETF04S-M3

Single Diodes Overview

The VS-20ETF04S-M3 is a surface mount fast soft recovery rectifier diode manufactured by Vishay Semiconductors. It features a glass passivated pellet chip junction and operates in a D2PAK (TO-263AB) package with a single circuit configuration. The device supports a maximum average forward current of 20 A at a case temperature of 97 °C and withstands a maximum peak reverse voltage of 400 V. Key electrical characteristics include a forward voltage drop of 1.3 V at 20 A, a reverse recovery time of 60 ns, and a snap factor of 0.6. It endures a non-repetitive surge current of up to 300 A and functions within a junction temperature range of -40 °C to +150 °C.

Single Diodes Feature Summary

• Glass passivated pellet chip junction ensures stable operation under severe temperature and power cycling conditions.
• Optimized for combined short reverse recovery time and low forward voltage drop.
• Designed and qualified according to JEDEC standards.

Single Diodes Applications

• Output rectification and freewheeling in inverters, choppers, and converters
• Input rectifications where severe restrictions on conducted EMI should be met

Single Diodes Procurement Notes

Verify the specific part number against official Vishay documentation to confirm compliance with RoHS directives and lead-free termination requirements. Ensure that the ordering suffix matches the desired packaging format, such as tube or tape and reel, as these variations affect handling procedures. Cross-reference thermal resistance values with the intended PCB footprint design to maintain safe operating temperatures during continuous DC operation.

Single Diodes Selection Notes

Select this component when applications require a balance between low conduction losses and rapid switching speeds. The D2PAK package provides efficient heat dissipation through the base cathode, suitable for high-current scenarios. Evaluate the snap factor and reverse recovery charge to ensure compatibility with sensitive control circuits and minimize electromagnetic interference generation during commutation events.
