AU2PKHM3_A/H

Overview

The AU2PKHM3_A/H is a fast recovery rectifier from Vishay Semiconductors, featuring an avalanche capability and AEC-Q101 qualification. It operates with a forward current of 2 A and a repetitive peak reverse voltage of 800 V. The device exhibits a maximum forward voltage of 2.1 V at 2 A and a typical reverse leakage current of 270 nA. Its ultrafast recovery time is 50 ns, supporting high-frequency applications. The component withstands a maximum surge current of 30 A and functions within a junction temperature range of -55 °C to +175 °C. It is housed in the SMPC (TO-277A-3) surface-mount package.

Feature Summary

• Features avalanche capability for robust operation under transient conditions
• Utilizes oxide planar chip junction technology for reliability
• Qualified for automotive applications per AEC-Q101 standards
• Designed for automated placement with a low-profile SMPC package

Applications

• Automotive power supply circuits requiring high voltage isolation
• High-frequency DC-DC converters and synchronous rectification
• Industrial motor drive protection stages
• Uninterruptible power supply (UPS) input rectification

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with required packaging and marking specifications. Confirm that the AEC-Q101 qualification status meets your project's automotive reliability standards. Check for any recent product change notices regarding material composition or manufacturing site updates. Ensure the ordering quantity aligns with the manufacturer's standard reel quantities to avoid handling discrepancies.

Selection Notes

Select this component when designing circuits that demand high reverse voltage blocking combined with fast switching speeds. The 800 V rating makes it suitable for mains-derived power supplies. Consider the 2 A average current limit for thermal management in compact enclosures. The SMPC package offers a balance between current handling capacity and board space efficiency compared to larger through-hole alternatives.

Part Context

This part belongs to Vishay's eSMP series of surface mount rectifiers. The series emphasizes low profile and high reliability for modern electronics. The AU2P prefix indicates a specific family of ultrafast recovery devices optimized for high-efficiency power conversion. These components are engineered to replace traditional through-hole diodes in space-constrained designs.

Replacement Considerations

Consult the official Vishay cross-reference guide for verified substitutes. Ensure any replacement matches the 800 V reverse voltage and 2 A forward current ratings. Verify that alternative packages maintain compatible footprint dimensions for direct PCB integration.
