Overview
The Vishay AR3PKHM3/87A is a single fast recovery rectifier diode housed in an SMPC (TO-277A-3) package. It features a maximum repetitive peak reverse voltage of 800 V and an average forward current rating of 3 A. The device exhibits a maximum forward voltage drop of 1.04 V at the rated current and a low leakage current of 330 nA. Designed for high-temperature operation, it supports junction temperatures up to +175 °C and includes avalanche ruggedness capabilities.
Feature Summary
- Fast recovery performance suitable for high-frequency switching applications
- Avalanche-rated construction for enhanced robustness against transient energy events
- High thermal stability with a maximum operating junction temperature of +175 °C
Applications
- Automotive power supply circuits requiring AEC-Q101 qualification
- High-voltage DC-DC converter stages
- Inductive load freewheeling protection
Procurement Notes
Verify the specific suffix /87A corresponds to the required reel packaging configuration when ordering. Confirm that the 800 V reverse voltage and 3 A current ratings align with the target circuit design requirements. Ensure compatibility with the SMPC footprint during PCB layout validation.
Selection Notes
Select this component for designs demanding high blocking voltage combined with fast switching speeds. The TO-277A package offers a compact surface-mount solution compared to traditional axial leads. Consider the avalanche capability if the application involves significant inductive kickback or transient voltage spikes.
Part Context
This part belongs to Vishay's AR3P series of automotive-grade fast recovery rectifiers. These devices are engineered to meet stringent reliability standards for automotive electronics. The series utilizes silicon planar technology to ensure consistent performance across varying thermal conditions.
Replacement Considerations
Consult official Vishay documentation for qualified cross-reference part numbers. Verify pinout compatibility and electrical parameter equivalence before substituting.
