Overview
The AU2PDHM3/87A is a fast recovery rectifier from Vishay Semiconductors, housed in an SMPC (TO-277A-3) surface-mount package. It features a single diode configuration with a maximum repetitive peak reverse voltage of 200 V and a continuous forward current rating of 2 A. The device exhibits a typical forward voltage of 1.13 V and a low reverse leakage current of 300 nA. Designed for high reliability, it supports a maximum non-repetitive peak forward surge current of 30 A and operates within a junction temperature range of -55°C to +175°C. The component is qualified under the AEC-Q101 automotive standard.
Feature Summary
- Fast recovery rectifier technology optimized for high-frequency switching applications
- Automotive-grade qualification ensuring reliability in demanding environments
- Junction passivation design provides robust protection against mechanical stress
Applications
- Automotive power supply circuits requiring high reliability
- High-frequency DC-DC converter topologies
- General-purpose rectification in industrial electronics
Procurement Notes
Verify the specific suffix /87A corresponds to the required reel packaging quantity when ordering. Confirm that the AEC-Q101 qualification meets your specific automotive application standards. Ensure the SMPC footprint matches your PCB layout constraints. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.
Selection Notes
Select this component for applications requiring fast recovery characteristics combined with automotive reliability standards. The 200 V rating suits low-voltage DC systems. Consider the thermal performance of the TO-277A package for heat dissipation needs. Compare the 66 ns recovery time against system switching frequency requirements to minimize switching losses effectively.
Part Context
This part belongs to the AU2P series of avalanche-rated fast recovery rectifiers by Vishay. The series utilizes eSMP technology for improved performance in surface-mount designs. These devices are engineered to handle transient energy events while maintaining stable rectification properties in compact form factors suitable for modern electronic assemblies.
Replacement Considerations
Direct substitutes include other Vishay AU2P series variants with matching electrical ratings. Verify pinout compatibility and thermal resistance values before substitution. Ensure any replacement maintains the same AEC-Q101 qualification if used in automotive contexts.
