AS4PGHM3/87A

Overview

The AS4PGHM3/87A is a surface-mount rectifier from Vishay General Semiconductor, housed in the TO-277A (SMPC) package. It features a dual anode configuration with a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 4 A per anode. The device utilizes standard recovery technology with a typical forward voltage drop of 1.1 V at 3.0 A. It is designed for high efficiency and low power losses, operating within a junction temperature range of -55°C to +150°C.

Feature Summary

• Dual anode configuration for flexible circuit integration
• Standard recovery technology optimized for general-purpose rectification
• Low thermal resistance and high current density design
• Compliant with RoHS directives and halogen-free standards

Applications

• General purpose rectification in power supplies
• DC-DC converter circuits
• Automotive electronics applications requiring AEC-Q101 qualification

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical characteristics and packaging options. Ensure compatibility with automated placement equipment due to the low-profile SMPC package dimensions. Confirm that the selected variant meets all required environmental and safety certifications for the target application.

Selection Notes

Select this component for designs requiring a compact, high-current dual-anode solution in a surface-mount format. The 400 V rating suits medium-voltage applications, while the 4 A capacity supports moderate power levels. Consider the standard recovery speed for non-high-frequency switching environments where cost and simplicity are prioritized over ultra-fast performance.

Part Context

This part belongs to Vishay's eSMP series of high current density surface mount Schottky barrier rectifiers, although it utilizes standard recovery technology rather than Schottky barriers. The TO-277A package provides a robust mechanical structure and efficient heat dissipation compared to smaller SMD packages, making it suitable for industrial and automotive environments.
