AR4PJHM3/87A

Overview

The AR4PJHM3/87A is a fast switching avalanche surface-mount rectifier from Vishay General Semiconductor. It features a maximum repetitive peak reverse voltage of 600 V and an average forward current rating of 4.0 A. The device exhibits a typical reverse recovery time of 140 ns and supports a peak forward surge current of 65 A. It operates within a junction temperature range of -55 °C to +175 °C and is housed in an SMPC (TO-277A) package.

Feature Summary

• Glass passivated pellet chip junction for enhanced reliability
• Controlled avalanche characteristics with specified energy ratings
• Low leakage current and high forward surge capability
• Automotive grade qualification available under AEC-Q101 standards

Applications

• Fast switching rectification in power supplies
• Inverters and converters
• Freewheeling diodes for consumer, automotive, and telecommunication equipment
• Lighting applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details and revision codes. Confirm that the HM3 designation aligns with halogen-free and RoHS compliance requirements. Ensure the selected variant matches the required AEC-Q101 automotive qualification status if applicable to the target application environment.

Selection Notes

Select this component for circuits requiring fast reverse recovery and avalanche ruggedness. The 600 V rating suits medium-voltage applications. Evaluate thermal resistance values relative to the PCB pad layout to ensure adequate heat dissipation. Verify compatibility with automated placement processes due to the low profile design.

Part Context

This part belongs to the eSMP® Series of fast switching avalanche rectifiers. It shares the SMPC (TO-277A) package form factor with other variants in the AR4 series, such as AR4PD and AR4PG, which offer different voltage ratings. The HM3 suffix indicates compliance with environmental standards and whisker test requirements.
