AR4PGHM3/86A

Overview

The AR4PGHM3/86A is a standard recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a 400 V reverse voltage rating and supports an average forward current of 4 A. The device utilizes the eSMP package (TO-277A-3) for surface mount installation. Key electrical characteristics include a maximum forward voltage of 1.1 V at 4 A, a peak repetitive reverse current of 10 uA, and a typical reverse recovery time of 2.5 us. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Standard recovery rectifier technology optimized for general-purpose power conversion applications
• Integrated ESD protection capabilities inherent to the eSMP package design
• Automotive-grade qualification compliant with AEC-Q101 standards

Applications

• Automotive electronics systems requiring robust rectification
• General-purpose power supply circuits
• DC-DC converter topologies

Procurement Notes

Verify the specific suffix /86A against official datasheets to confirm reel packaging specifications. Ensure compatibility with SMD/SMT assembly processes using the TO-277A-3 footprint. Confirm RoHS compliance status through manufacturer documentation prior to integration into production lines.

Selection Notes

Select this component when a 4 A current rating and 400 V blocking capability are required in a compact surface-mount form factor. The eSMP package offers thermal performance advantages over traditional leaded packages. Consider the 2.5 us reverse recovery time for frequency constraints in switching applications.

Part Context

This part belongs to the AR4P series of standard recovery rectifiers from Vishay. These devices are designed for high reliability in automotive and industrial environments. The eSMP package provides a low-profile solution suitable for space-constrained printed circuit board layouts while maintaining adequate heat dissipation capabilities.

Replacement Considerations

Consult official substitution guides for equivalent parts within the Vishay portfolio or cross-manufacturer alternatives that match the 4 A, 400 V, and TO-277A-3 package requirements.
