AS4PDHM3/87A

Overview

The AS4PDHM3/87A is a single standard recovery rectifier from Vishay Semiconductors, housed in an SMPC (TO-277A-3) surface-mount package. It features a maximum repetitive peak reverse voltage of 200 V and an average forward current rating of 4 A. The device exhibits a typical forward voltage drop of 920 mV at the rated current and supports a maximum surge current of 100 A. Reverse leakage current is specified at 350 nA, with a typical reverse recovery time of 1.8 µs. It operates within a junction temperature range of -55 °C to +175 °C and holds AEC-Q101 qualification.

Feature Summary

Avalanche-rated construction for robust operation under transient overvoltage conditions
High-temperature capability with a maximum junction temperature of 175 °C
Designed for automated surface-mount placement via the low-profile SMPC package

Applications

Automotive electronics requiring AEC-Q101 qualified components
General-purpose rectification in industrial power supplies
DC-DC converter output stages

Procurement Notes

Verify the specific suffix /87A against the manufacturer datasheet to confirm reel packaging specifications. Ensure the component matches the required avalanche rating and thermal characteristics for the target application environment. Cross-reference the AEC-Q101 certification status if automotive compliance is mandatory for the design.

Selection Notes

Select this component when a single diode configuration with 200 V blocking capability and 4 A continuous current is required. The choice is driven by the need for high-temperature operation up to 175 °C and avalanche ruggedness. Consider the TO-277A footprint compatibility with existing PCB layouts and the requirement for standard recovery characteristics rather than ultra-fast switching.

Part Context

This part belongs to Vishay's eSMP series of surface-mount rectifiers. The series utilizes the TO-277A (SMPC) package to provide high current density in a compact form factor suitable for modern automated assembly processes. The AS4P designation indicates a 4 A standard recovery device within this product family.
