AR3PK-M3/86A

Overview

The AR3PK-M3/86A is an avalanche-rated rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 1.6 A. The device utilizes the TO-277A (SMPC) surface-mount package, designed for high-reliability applications requiring avalanche energy capability.

Feature Summary

• Incorporates avalanche rating for robust operation under transient overvoltage conditions
• Utilizes eSMP® package technology for compact surface-mount integration
• Designed with low thermal resistance for efficient heat dissipation

Applications

• High-voltage power supply circuits
• Inductive load switching protection
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix /86A against the official Vishay datasheet to confirm package variant and tape-and-reel specifications. Ensure compatibility with RoHS3 directives and check for any recent PCN updates regarding manufacturing site or material changes before finalizing procurement.

Selection Notes

Select this component when circuit design requires a single-diode configuration with explicit avalanche energy handling capabilities at 800 V. Compare thermal performance and package dimensions against alternative SMPC variants to ensure mechanical fit and adequate heat sinking for the target application's duty cycle.

Part Context

This part belongs to the AR3P series of avalanche rectifiers from Vishay. It shares the eSMP® package family with other Vishay diodes but is distinct in its avalanche specification compared to standard recovery rectifiers like the AS3P series. It serves as a specialized solution for protecting circuits from inductive kickback.
