AU1PK-M3/85A

Overview

The AU1PK-M3/85A is a single ultra-fast recovery rectifier diode manufactured by Vishay Semiconductors. It features an 800 V reverse voltage rating and supports a continuous forward current of 1 A. The device utilizes the eSMP (DO-220AA) surface-mount package. Key electrical characteristics include a maximum forward voltage of 1.5 V, a peak surge current capacity of 30 A, and a very fast reverse recovery time of 75 ns. It operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

Ultra-fast recovery performance with 75 ns reverse recovery time for high-frequency efficiency
Avalanche rated construction enabling robust operation in inductive switching environments
Extended thermal capability supporting junction temperatures up to 175 °C

Applications

High-frequency power supply circuits
Free-wheeling diodes in DC-DC converters
Snubber circuits requiring rapid switching response

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with the target PCB footprint for the DO-220AA package. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration into regulated assemblies.

Selection Notes

Select this component when high blocking voltage and fast switching speeds are required in a compact surface-mount form factor. The avalanche rating makes it suitable for applications with potential inductive load transients. Compare the 75 ns recovery time against standard rectifiers to determine suitability for the specific switching frequency requirements of the design.

Part Context

This part belongs to the AU1P series of ultra-fast recovery rectifiers from Vishay. These devices are designed for general-purpose rectification in demanding electronic applications where speed and voltage handling are critical. The eSMP package provides a reliable surface-mount solution for automated assembly processes.
