VS-40EPF04-M3

Single Diodes Overview

The VS-40EPF04-M3 is a fast soft recovery rectifier diode from Vishay Semiconductors, rated for a maximum average forward current of 40 A and a maximum peak reverse voltage of 400 V. It features a low forward voltage drop of 1 V at 10 A and a short reverse recovery time of 60 ns. The device operates within a junction temperature range of -40 °C to +150 °C and withstands a non-repetitive surge current of up to 475 A. Packaged in a TO-247AC 2L through-hole case with a base cathode configuration, it utilizes glass passivation for stable operation under severe thermal cycling.

Single Diodes Procurement Notes

Verify the specific part number against official Vishay documentation to confirm electrical ratings and package details before procurement. Ensure compliance with RoHS and REACH directives as indicated by the M3 suffix. Confirm that the ordering quantity aligns with manufacturer packaging specifications, typically provided in tubes. Validate technical parameters directly with authorized distributors or the manufacturer to ensure accuracy for your specific circuit requirements.

Single Diodes Selection Notes

Select this component when designing circuits requiring fast soft recovery characteristics to minimize switching losses and EMI. The 40 A current rating and 400 V blocking capability suit medium-power industrial applications. Consider the TO-247AC package for efficient heat dissipation via the base cathode. Evaluate thermal resistance values to determine appropriate heatsinking for maintaining junction temperatures within safe operating limits under expected load conditions.
