AU1PG-M3/85A

Single Diodes Overview

The AU1PG-M3/85A is a surface-mount avalanche-rated ultrafast recovery rectifier from Vishay, housed in the DO-220AA (SMP) package. It features a maximum repetitive reverse voltage of 400 V and an average forward rectified current of 1 A. The device exhibits a low forward voltage of 1.85 V at 1 A and a fast reverse recovery time of 75 ns. Designed for high reliability, it supports a maximum junction temperature of 175°C and includes avalanche capability for robust operation in inductive switching applications.

Single Diodes Feature Summary

• Avalanche-rated construction for enhanced ruggedness
• Ultrafast recovery characteristics minimizing switching losses
• High thermal stability with elevated junction temperature rating

Single Diodes Applications

• High-frequency DC-DC converters
• Free-wheeling diodes in inductive circuits
• Snubber circuits requiring avalanche tolerance

Single Diodes Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with design requirements. Confirm that the DO-220AA footprint matches the PCB layout. Check for RoHS compliance status and ensure the ordering quantity aligns with standard reel specifications provided by authorized distributors.

Single Diodes Selection Notes

Select this component when avalanche energy handling is required alongside ultrafast switching speeds. The 400V rating suits medium-voltage applications, while the 1A current capacity fits compact power stages. Ensure thermal management strategies account for the 175°C junction limit during peak load conditions.

Single Diodes Part Context
