AR3PGHM3/87A

Overview

The AR3PGHM3/87A is a single fast recovery avalanche rectifier from Vishay, housed in a TO-277A (SMPC) surface-mount package. It features a 400 V reverse voltage rating and a 1.8 A forward current capability. Key electrical parameters include a maximum forward voltage of 1.04 V, a peak repetitive reverse current of 330 nA, and a typical reverse recovery time of 122 ns. The device supports a maximum surge current of 50 A and operates within a junction temperature range of -55 °C to +175 °C. It is qualified under the AEC-Q101 standard for automotive reliability.

Feature Summary

• Incorporates avalanche ruggedness for enhanced robustness against transient energy events
• Utilizes eSMP (enhanced Small Molded Package) technology for compact surface-mount integration
• Fast recovery characteristics designed to minimize switching losses in high-frequency applications

Applications

• Automotive power supply circuits requiring AEC-Q101 compliance
• DC-DC converter output rectification stages
• High-efficiency freewheeling diode applications in industrial electronics

Procurement Notes

Verify the specific suffix /87A indicates reel packaging configuration as per official datasheets. Confirm RoHS compliance status and REACH SVHC declarations directly with the manufacturer or authorized distributors before procurement. Ensure the ordering part number matches the exact electrical specifications required for the target design to avoid compatibility issues.

Selection Notes

Select this component when a single-phase fast recovery rectifier with avalanche capability is required in a TO-277A footprint. The 400 V rating suits medium-voltage DC bus applications. Consider the 1.8 A continuous current limit and 122 ns recovery time for thermal and efficiency calculations. Verify that the operating temperature range meets the environmental constraints of the final assembly.

Part Context

This device belongs to the AR3P series of fast recovery rectifiers manufactured by Vishay General Semiconductor. The series utilizes advanced silicon planar technology to achieve low forward voltage drop and fast switching speeds. The TO-277A package provides a balance between thermal performance and board space efficiency, suitable for automated surface-mount assembly processes.

Replacement Considerations

Cross-reference with AR3PGHM3_A/H for identical electrical specifications but potentially different packaging or trailing zeros. Check AR3PDHM3/87A for similar form factor but verify if pinout or specific avalanche ratings differ. Always consult official substitution guides to ensure functional equivalence.
