AU3PK-M3/86A

Overview

The AU3PK-M3/86A is an Avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 800 V and an average forward rectified current (Io) of 1.4 A. The device utilizes the TO-277A (SMPC) surface mount package. Key electrical parameters include a reverse recovery time (trr) of 75 ns and a junction temperature range of -55°C to 175°C.

Feature Summary

• Incorporates avalanche ruggedness for enhanced reliability under transient conditions
• Utilizes eSMP® TO-277A surface mount packaging for compact board integration
• Designed with low thermal resistance characteristics suitable for high-power applications

Applications

• Flyback diodes in inductive load switching circuits
• Protection against voltage spikes in power supply outputs
• Snubber circuits in high-voltage switching applications

Procurement Notes

Verify the specific suffix /86A corresponds to the required reel quantity and tape-and-reel configuration for your assembly line. Confirm RoHS compliance status and lead-free specifications match your manufacturing requirements. Cross-reference the datasheet revision date to ensure parameter accuracy before finalizing component selection.

Selection Notes

Select this component when an 800 V rating and 1.4 A continuous current capacity are required in a small surface-mount footprint. The 75 ns reverse recovery time makes it suitable for moderate-speed switching applications. Ensure the circuit design accounts for the avalanche energy ratings specified in the official datasheet to prevent device failure during transient events.

Part Context

This part belongs to Vishay's eSMP® series, which offers standard rectifiers and specialized diodes in the compact TO-277A package. The AU3PK variant specifically addresses avalanche requirements within this form factor, providing a solution for designers needing robust protection in space-constrained high-voltage designs without sacrificing current handling capabilities.
