AS4PGHM3/86A

Overview

The AS4PGHM3/86A is a surface-mount standard recovery rectifier from Vishay General Semiconductor, housed in the TO-277A (SMPC) package. It features a 400 V maximum repetitive reverse voltage and supports an average forward current of 4 A. The device exhibits a typical forward voltage of 1.1 V at full load and handles a maximum surge current of 100 A. Designed for high reliability, it operates within a junction temperature range of -55°C to +150°C and meets AEC-Q101 automotive qualification standards.

Feature Summary

Integrated avalanche ruggedness capability for enhanced circuit protection
Automotive-grade construction compliant with AEC-Q101 standards
High current density design utilizing eSMP packaging technology

Applications

Automotive power supply circuits requiring avalanche tolerance
General-purpose rectification in industrial electronics
DC-DC converter output stages

Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required packaging options and terminal finishes. Confirm that the selected variant aligns with the intended thermal management strategy and PCB layout constraints for the TO-277A footprint.

Selection Notes

Select this component when a single diode requires both standard recovery characteristics and avalanche energy handling capabilities. The TO-277A package offers a compact form factor suitable for automated assembly processes while providing sufficient thermal dissipation for 4 A continuous operation in constrained spaces.

Part Context

This part belongs to Vishay's eSMP series of surface-mount rectifiers, designed to replace larger through-hole components. The series emphasizes low profile and high reliability for modern electronic manufacturing. The AS4PGHM3 variant specifically integrates avalanche rating into the standard 400 V, 4 A performance envelope.
