AU2PKHM3/86A

Overview

The AU2PKHM3/86A is a fast recovery rectifier manufactured by Vishay Semiconductors, housed in an SMPC (TO-277A-3) surface-mount package. It features a single cathode dual anode configuration with an 800 V reverse voltage rating and a 2 A average forward current. The device exhibits a 50 ns maximum recovery time and a 2.1 V forward voltage drop at rated current. It supports a peak non-repetitive surge current of 30 A and operates within a junction temperature range of -55°C to +175°C. The component is AEC-Q101 qualified for automotive applications.

Feature Summary

• Features ultrafast recovery characteristics suitable for high-frequency switching applications
• Includes avalanche capability for robust operation under transient conditions
• Utilizes oxide planar chip junction technology for reliability
• Complies with RoHS directives and WEEE standards

Applications

• Automotive power supply circuits
• High-frequency DC-DC converters
• Industrial motor drive systems

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and packaging variants. Ensure the procurement channel provides valid traceability records for AEC-Q101 qualified components. Confirm that the received units match the specified TO-277A package dimensions and pinout configuration before integration into production lines.

Selection Notes

Select this component when designing circuits requiring high voltage blocking capabilities combined with fast switching speeds. The single cathode dual anode topology allows for efficient bridge or center-tapped configurations in compact surface-mount layouts. Consider the thermal management requirements associated with the 2 A continuous current rating in enclosed environments.

Part Context

This part belongs to the AU2P series of ultrafast rectifiers from Vishay. It shares the eSMP branding and TO-277A physical footprint with other devices in the family, such as the AU2PK-M3/86A. The series is designed to replace bulkier through-hole alternatives while maintaining high performance in modern electronic assemblies.

Replacement Considerations

Direct substitutes include the AU2PK-M3/86A and AU2PKHM3_A/H. Verify pin compatibility and electrical ratings before substitution.
