AR3PMHM3_A/H

Overview

The AR3PMHM3_A/H is a fast switching avalanche surface-mount rectifier manufactured by Vishay General Semiconductor. It features a single diode configuration in an SMPC (TO-277A) package with glass passivated pellet chip junctions. The device supports a maximum repetitive peak reverse voltage of 1000 V and a maximum DC forward current of 3.0 A. Key electrical characteristics include a typical reverse recovery time of 120 ns, a non-repetitive avalanche energy rating of 20 mJ at IAS = 2.5 A, and a peak forward surge current capability of 50 A. It operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

Controlled avalanche characteristics for robust performance under transient conditions
Fast reverse recovery time suitable for high-frequency applications
Low leakage current and low forward voltage drop
High forward surge current capability

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 the manufacturer's documentation to confirm packaging details and revision status. Ensure that the HM3 designation aligns with required halogen-free and RoHS compliance standards. Confirm AEC-Q101 qualification requirements if the application targets automotive sectors. Cross-reference the base part number with official Vishay datasheets to validate technical parameters before procurement.

Selection Notes

Select this component for applications requiring fast switching capabilities and avalanche ruggedness in a compact surface-mount form factor. The SMPC package offers a low profile ideal for automated placement. Consider the thermal resistance and derating curves when designing for high ambient temperatures or continuous high-current loads. Verify compatibility with PCB pad layouts specified in the mechanical data section.

Part Context

This component belongs to the eSMP® series of fast switching avalanche rectifiers from Vishay. It shares the SMPC (TO-277A) package with other variants like the AR3PKHM3. The HM3 suffix indicates compliance with JESD 201 class 2 whisker test requirements and denotes an AEC-Q101 qualified version compared to the commercial grade M3 variant.
