AU2PD-M3/86A

Overview

The AU2PD-M3/86A is a single avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage of 200 V and an average forward current rating of 1.6 A to 2 A, depending on the specific datasheet reference. The device utilizes a surface-mount TO-277A (SMPC) package with three pins. Key electrical characteristics include a reverse recovery time of 75 ns and a junction operating temperature range from -55°C to +175°C. This component is designed for robust switching applications requiring avalanche capability.

Feature Summary

• Incorporates avalanche ruggedness for enhanced reliability in inductive switching environments
• Utilizes SMPC (TO-277A) surface-mount packaging for compact board integration
• Supports high junction temperatures up to 175°C for demanding thermal conditions

Applications

• Inductive load switching circuits
• Flyback diode protection in power supplies
• High-frequency rectification applications

Procurement Notes

Verify the specific datasheet version for the AU2PD-M3/86A to confirm exact current ratings, as sources indicate variations between 1.6 A and 2 A. Ensure the TO-277A footprint matches the design layout. Confirm RoHS compliance status through official Vishay documentation before finalizing procurement specifications.

Selection Notes

Select this component when avalanche capability is required for a single-diode configuration in a low-profile SMD package. Compare the 200 V reverse voltage rating against circuit peak inverse voltage requirements. Consider the 75 ns reverse recovery time for compatibility with the target switching frequency and ensure the TO-277A thermal dissipation meets system heat management needs.

Part Context

This part belongs to Vishay's discrete diode portfolio, specifically within the avalanche-rated segment. It serves as a specialized alternative to standard rectifiers where transient energy absorption is critical. The TO-277A package provides a balance between current handling capacity and space efficiency for modern electronic assemblies.
