AS3PKHM3/87A

Overview

The AS3PKHM3/87A is a single standard rectifier diode from Vishay Semiconductors, housed in an SMPC (TO-277A-3) surface-mount package. It features a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 3 A. The device exhibits a maximum forward voltage drop of 900 mV at the rated current and supports a non-repetitive peak forward surge current of 70 A. It operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

• Features avalanche capability for robust operation under transient conditions
• Utilizes eSMP packaging technology for compact surface-mount integration
• Designed with high thermal stability for demanding environments

Applications

• Automotive power supply circuits requiring AEC-Q101 qualification
• General-purpose rectification in industrial electronics
• High-voltage DC-DC converter stages

Procurement Notes

Verify the specific suffix /87A against official datasheets to confirm reel packaging specifications. Ensure compatibility with TO-277A-3 footprint requirements during PCB layout. Confirm RoHS compliance status through manufacturer documentation prior to procurement.

Selection Notes

Select this component when a single high-voltage rectifier is required in a compact SMD form factor. The 800 V rating suits applications exceeding standard low-voltage limits. Consider the 3 A current capacity and avalanche ruggedness for reliable performance in automotive or industrial power systems.

Part Context

This part belongs to the AS3P series of standard rectifiers manufactured by Vishay Semiconductors. The series utilizes eSMP packaging to provide a smaller, lighter, and stronger alternative to traditional through-hole packages while maintaining high reliability standards for electronic assemblies.

Replacement Considerations

AS3PKHM3_A/H is a verified substitute offering identical electrical characteristics and package configuration.
