AU2PMHM3_A/H

Overview

The AU2PMHM3_A/H is an ultrafast avalanche surface mount rectifier manufactured by Vishay General Semiconductor. It features a single diode configuration in an SMPC (TO-277A) package with glass passivated pellet chip junctions. The device supports a maximum repetitive peak reverse voltage of 1000 V and a maximum DC forward current of 2.0 A. Key electrical parameters include a typical reverse recovery time of 75 ns, a peak forward surge current of 30 A, and a non-repetitive avalanche energy rating of 20 mJ at TJ = 25 °C. It operates within a temperature range of -55 to +175 °C.

Feature Summary

• Ultrafast reverse recovery characteristics for high-speed switching applications
• Controlled avalanche capability with specified energy ratings
• Glass passivated junction providing stable performance and low leakage current
• Low profile construction suitable for automated placement processes

Applications

• Fast switching rectification in power supplies

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm the exact revision level and packaging format. Ensure that the procurement specifications align with the required AEC-Q101 qualification status if automotive compliance is mandated for the target application environment.

Selection Notes

Select this component when designing circuits requiring high-voltage blocking capabilities combined with fast recovery speeds. Consider the thermal resistance values and derating curves to ensure reliable operation under expected load conditions. Validate that the avalanche energy requirements of the circuit fall within the specified limits for safe operation.

Part Context

This part belongs to the eSMP series of ultrafast rectifiers designed for surface mount technology. It utilizes the SMPC package to provide robust mechanical stability and efficient heat dissipation. The product line is engineered to meet stringent automotive reliability standards while maintaining compatibility with standard industrial manufacturing processes.

Replacement Considerations

Direct substitutes within the same family include the AU2PKHM3_A/H variant, which offers similar characteristics but with an 800 V reverse voltage rating instead of 1000 V. Verify pinout compatibility and thermal performance before implementing any cross-reference replacements.
