AR3PG-M3/87A

Overview

The AR3PG-M3/87A is a standard recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a 400 V maximum reverse voltage and a 1.8 A average forward current rating. The device utilizes the TO-277A-3 (SMPC) surface-mount package. Key electrical parameters include a maximum forward voltage of 1.1 V at 1.8 A, a peak non-repetitive surge current of 50 A, and a maximum reverse leakage current of 5 µA at rated voltage. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Engineered with avalanche-rated capability for robust operation under transient overvoltage conditions
• Utilizes eSMP® technology for high reliability in compact surface-mount designs
• Features low forward voltage drop to minimize conduction losses
• Compliant with RoHS standards and free from halogenated substances

Applications

• Automotive power supply circuits requiring avalanche ruggedness
• General-purpose rectification in industrial electronics
• Protection stages in DC-DC converter topologies

Procurement Notes

Verify the specific suffix /87A corresponds to the reel packaging configuration required for your assembly line. Confirm that the TO-277A-3 footprint matches your PCB design guidelines. Ensure compliance with REACH SVHC declarations as specified in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when an avalanche-rated diode is necessary for handling inductive load switching or fault conditions. The 1.8 A current rating suits moderate power applications where space constraints favor the SMPC package over larger through-hole alternatives. Verify thermal management requirements for the intended operating environment.
