AR4PMHM3/86A

Overview

The AR4PMHM3/86A 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. Key electrical parameters include a maximum repetitive peak reverse voltage of 1000 V, a maximum DC forward current of 4.0 A, and a peak forward surge current of 65 A. The device exhibits a typical reverse recovery time of 79 ns and a maximum of 120 ns. Forward voltage is rated at 1.27 V at 4.0 A. Non-repetitive avalanche energy capability is specified at 20 mJ. Operating junction and storage temperature range spans from -55 °C to +175 °C.

Feature Summary

Low leakage current performance

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 suffix against the manufacturer's official documentation to confirm compliance status. The HM3 suffix indicates AEC-Q101 qualification and halogen-free composition, while M3 denotes commercial grade. Ensure the package code matches the required reel size for automated placement processes. Cross-reference the base part number with the latest datasheet revision to validate thermal and electrical specifications before finalizing procurement.

Selection Notes

Select this component for designs requiring high voltage blocking capabilities combined with fast switching speeds. The avalanche rating allows for robustness against transient energy events in inductive loads. Consider the SMPC package dimensions for PCB layout constraints. Verify that the operating temperature range meets the environmental requirements of the target application. Evaluate thermal resistance values to ensure adequate heat dissipation under continuous load conditions.

Part Context

This device belongs to the AR4P series of fast switching avalanche rectifiers from Vishay. It utilizes the eSMP package technology, which offers a low profile ideal for automated surface mount assembly. The series includes variants with different voltage ratings, such as the AR4PK for 800 V applications. The construction involves a glass passivated chip junction housed in a UL 94 V-0 rated molding compound.

Replacement Considerations

Direct substitutes within the same family include AR4PKHM3 for lower voltage requirements. Other Vishay SMPC packages like VS-6ESU06HM3 offer similar form factors but differ in current and speed specifications. Verify pinout compatibility and thermal characteristics when considering alternative manufacturers' components.
