AS3PDHM3/87A

Overview

The AS3PDHM3/87A is a fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common cathode configuration housed in an SMPC (TO-277A-3) surface-mount package. The device is rated for a maximum repetitive peak reverse voltage of 800 V and supports an average forward rectified current of 3 A. Key electrical parameters include a maximum forward voltage of 1.5 V at the rated current, a maximum non-repetitive peak surge current of 60 A, and a typical reverse leakage current of 5 µA at full rated voltage. The component is qualified to the AEC-Q101 standard for automotive applications.

Feature Summary

• Dual common cathode configuration for efficient bridge or center-tap circuit topologies
• Fast recovery characteristics optimized for high-frequency switching operations
• Automotive-grade reliability with AEC-Q101 qualification
• Low-profile surface-mount packaging suitable for automated placement

Applications

• Automotive DC-DC converter circuits
• High-frequency power supply rectification
• Industrial motor drive freewheeling paths
• General-purpose rectification in compact electronic assemblies

Procurement Notes

Verify the specific suffix /87A against the manufacturer's official datasheet to confirm reel packaging specifications. Ensure the ordering part number matches the exact voltage and current ratings required for the target application. Cross-reference the AEC-Q101 qualification status if the design mandates automotive compliance standards. Confirm RoHS and REACH compliance documentation is available for regulatory adherence.

Selection Notes

Select this component when a dual common cathode topology is required within a compact surface-mount footprint. The 800 V rating provides sufficient headroom for high-voltage bus applications. Consider the thermal resistance of the TO-277A-3 package for heat dissipation requirements. Evaluate the fast recovery time against the switching frequency of the intended power stage to minimize switching losses.

Part Context

This component belongs to Vishay's eSMP series of high-current density surface mount rectifiers. The series utilizes the TO-277A (SMPC) package to deliver robust performance in space-constrained designs. These devices are engineered to meet the stringent reliability demands of modern electronics, including automotive and industrial sectors, offering a balance of high current handling and fast switching speeds.
