AR3PJHM3_A/I

Overview

The AR3PJHM3_A/I is a fast switching avalanche surface-mount rectifier from Vishay General Semiconductor. It features a single diode configuration in an SMPC (TO-277A) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 600 V, a maximum DC forward current of 3.0 A, and a peak forward surge current of 50 A. The device exhibits a typical reverse recovery time of 140 ns and a maximum instantaneous forward voltage of 1.6 V at 3.0 A. It operates within a junction temperature range of -55 to +175 °C and meets AEC-Q101 qualification standards.

Feature Summary

• Glass passivated pellet chip junction for enhanced reliability
• Controlled avalanche characteristics with high forward surge capability
• Low leakage current and fast reverse recovery time
• Halogen-free, RoHS-compliant construction

Applications

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

Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging details. The 'I' suffix indicates a 6500-unit delivery mode in a 13-inch diameter plastic tape and reel. Confirm that the HM3 designation aligns with required AEC-Q101 automotive qualification and material categorization compliance before finalizing procurement specifications.

Selection Notes

Select this component when a 600 V reverse voltage rating and 3 A continuous forward current are required in a low-profile surface-mount form factor. The controlled avalanche capability makes it suitable for applications experiencing transient energy events. Ensure the thermal management design accommodates the specified junction-to-ambient thermal resistance for reliable operation at elevated temperatures.

Part Context

This part belongs to the eSMP series of fast switching avalanche rectifiers manufactured by Vishay General Semiconductor. It shares the SMPC (TO-277A) package with other variants in the AR3P family, differentiated primarily by their voltage ratings. The HM3 suffix denotes an AEC-Q101 qualified version that is halogen-free and RoHS compliant, distinguishing it from commercial grade M3 versions.

Replacement Considerations

Direct substitutes within the same family include AR3PGHM3_A/I (400 V rating) and AR3PDHM3_A/I (200 V rating). Verify that the replacement maintains the required voltage margin and matches the physical footprint and pinout of the SMPC package.
