AU2PMHM3_A/I

Overview

The AU2PMHM3_A/I is an ultrafast avalanche surface mount rectifier from the eSMP series, manufactured by Vishay General Semiconductor. It features a single diode configuration in an SMPC (TO-277A) package with glass passivated pellet chip junctions. Key electrical parameters include a maximum repetitive peak reverse voltage of 1000 V and a maximum DC forward current of 1.3 A under pulsed conditions or 2.0 A continuous. The device exhibits a fast reverse recovery time of up to 75 ns and supports non-repetitive avalanche energy of 30 mJ at typical test currents. Operating temperatures range from -55 °C to +175 °C.

Feature Summary

• Ultrafast reverse recovery characteristics suitable for high-frequency switching applications
• Controlled avalanche capability allowing operation in inductive load switching scenarios
• Glass passivated junction providing robust protection against transient voltage stresses
• Low profile construction optimized for automated surface placement processes

Applications

• Fast switching rectification in power supply circuits
• Freewheeling diodes in consumer and automotive electronics
• Inverter and converter topologies requiring high voltage blocking
• Lighting driver circuits demanding rapid turn-off speeds

Procurement Notes

Verify the specific ordering code suffix to confirm packaging quantity and reel diameter. The AU2PMHM3_A/I designation indicates a 6500-unit delivery mode on a 13-inch diameter plastic tape and reel. Confirm that the HM3 suffix aligns with halogen-free and RoHS compliance requirements for your assembly process. Ensure the AEC-Q101 qualification status matches your automotive application standards before finalizing procurement orders.

Selection Notes

Select this component when circuit designs require a 1000 V blocking voltage combined with ultrafast recovery times below 75 ns. The SMPC package offers a compact footprint suitable for space-constrained PCB layouts. Consider the thermal resistance values when calculating heat dissipation for high ambient temperature environments. Verify that the forward surge current capability meets the peak inrush requirements of the target power stage.

Part Context

This part belongs to the AU2PK/AU2PM family of ultrafast avalanche rectifiers designed for surface mount technology. The eSMP series utilizes a TO-277A form factor to provide improved thermal performance compared to standard DO-214 packages. The product line targets modern power conversion systems where efficiency and switching speed are critical design constraints.

Replacement Considerations

Direct substitutes within the same family include the AU2PKHM3_A/I variant, which shares identical physical dimensions but offers an 800 V reverse voltage rating instead of 1000 V. Verify pinout compatibility and thermal resistance specifications when cross-referencing with other manufacturers' ultrafast rectifiers in the SMPC package style.
