AU2PG-M3/86A

Overview

The AU2PG-M3/86A is a surface-mount avalanche-rated rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 1.6 A. The device utilizes the eSMP® package (TO-277A), providing a compact form factor for high-density applications. It is designed with avalanche capability to withstand transient energy events, ensuring robust performance in inductive switching environments.

Feature Summary

• Incorporates avalanche rating for enhanced reliability during transient overvoltage conditions
• Utilizes eSMP® TO-277A surface-mount package for space-efficient PCB integration
• Engineered for high-speed switching applications with fast recovery characteristics

Applications

• High-frequency DC-DC converters requiring avalanche ruggedness
• Inductive load protection circuits
• Power supply output rectification in compact designs

Procurement Notes

Verify the specific suffix /86A against the official datasheet to confirm packaging configuration. Ensure the procurement channel provides traceable documentation confirming RoHS compliance and the active lifecycle status. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when circuit design demands both high reverse voltage blocking and avalanche energy handling capabilities in a small footprint. Compare thermal resistance values against system heat dissipation requirements. Evaluate the trade-off between the 1.6 A current rating and the desired efficiency levels in the target power stage application.

Part Context

This device belongs to Vishay's eSMP® series, which integrates standard rectifier functions into a highly compact surface-mount package. The series targets modern electronics where board space is limited but reliability under electrical stress remains critical. The AU2PG variant specifically addresses scenarios requiring avalanche tolerance within the SMPC form factor.

Replacement Considerations

Direct substitutes must match the 400 V reverse voltage, 1.6 A current rating, and TO-277A package. Verify that alternative components also possess avalanche ratings if transient immunity is required. Confirm pinout compatibility and thermal characteristics before implementation.
