AU2PDHM3_A/H

Overview

The AU2PDHM3_A/H is a fast recovery rectifier from Vishay Semiconductors, featuring a single configuration in a TO-277A (SMPC) surface-mount package. It supports a maximum average forward current of 2 A and a repetitive peak reverse voltage of 200 V. Key electrical parameters include a forward voltage of 1.13 V at rated current, a reverse leakage current of 300 nA, and a typical reverse recovery time of 66 ns. The device withstands a maximum surge current of 30 A and operates within a junction temperature range of -55 °C to +175 °C. It is qualified under the AEC-Q101 automotive standard.

Feature Summary

• Features avalanche-rated capability for robust performance in inductive switching applications.
• Utilizes oxide planar chip junction technology for high reliability and low leakage current.
• Designed with ultrafast recovery characteristics suitable for high-frequency power conversion.
• Complies with RoHS directives and is halogen-free according to IEC 61249-2-21 definitions.

Applications

• Automotive electronics systems requiring AEC-Q101 qualified components.
• High-frequency DC-DC converters and power supply circuits.
• Freewheeling diode applications in inductive load switching.
• General-purpose rectification in compact surface-mount designs.

Procurement Notes

Verify the specific suffix 'A/H' against official datasheets to confirm packaging and material compliance. Confirm AEC-Q101 qualification status directly with the manufacturer or authorized distributors. Ensure thermal management aligns with the specified operating temperature range. Cross-reference pinout configurations for the TO-277A package during PCB layout. Validate that the 200V rating meets the circuit's peak inverse voltage requirements.

Selection Notes

Select this component when a fast recovery rectifier with avalanche capability is required in a compact SMPC package. The 2 A current rating suits moderate power applications where space is constrained. Consider the 66 ns recovery time for efficiency in high-frequency switching environments. Verify compatibility with automated placement processes due to the low-profile design. Ensure the 200V blocking voltage exceeds the circuit's maximum transient voltages.

Part Context

This part belongs to the AU2P series of fast recovery rectifiers by Vishay Semiconductors. The series is characterized by its use in high-reliability applications, including automotive electronics. The TO-277A package provides a balance between current handling capacity and board space efficiency. The product line emphasizes compliance with environmental standards and automotive quality requirements.

Replacement Considerations

Consult official Vishay documentation for direct cross-references. Verify that any substitute matches the 2 A current, 200 V voltage, and TO-277A package constraints. Ensure equivalent reverse recovery time and avalanche ratings if applicable.
