AS4PKHM3_A/H

Overview

The AS4PKHM3_A/H is a standard recovery rectifier manufactured by Vishay Semiconductors. It features an 800 V repetitive peak reverse voltage and a 4 A average forward current rating. The device utilizes the eSMP (SMPC) package, specifically TO-277A-3, for surface mount installation. Key electrical parameters include a maximum forward voltage of 920 mV at rated current and a reverse leakage current of 350 nA. It supports a surge current of 100 A and operates within a junction temperature range of -55°C to +175°C. The component is qualified under AEC-Q101 standards.

Feature Summary

Equipped with avalanche capability for enhanced robustness in inductive switching applications.
Utilizes the eSMP (SMPC) surface-mount package design for efficient thermal dissipation.
Complies with AEC-Q101 qualification requirements for automotive electronics reliability.

Applications

Automotive power supply circuits requiring high-voltage rectification.
General-purpose rectification in industrial equipment.
High-reliability power conversion systems.

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm package type and qualification status. Ensure compatibility with automated placement equipment for the TO-277A-3 form factor. Confirm that the application environment respects the specified thermal limits and voltage ratings defined in the manufacturer datasheet.

Selection Notes

Select this component when a single-phase standard recovery diode with high voltage blocking capability is required. The choice is driven by the need for avalanche ruggedness and automotive qualification. Consider the thermal performance of the SMPC package relative to the expected load current and ambient conditions.

Part Context

This part belongs to the AS4P series of standard recovery rectifiers from Vishay. The series is designed for general-purpose applications where high voltage and moderate current are needed. The HM3 suffix indicates lead-free construction compliant with RoHS directives.
