AU2PM-M3/86A

Overview

The AU2PM-M3/86A is an ultrafast avalanche surface mount rectifier from Vishay General Semiconductor, part of the eSMP series. It features a glass passivated pellet chip junction and operates with a maximum repetitive peak reverse voltage of 1000 V and a DC forward current of 2.0 A. The device exhibits a fast reverse recovery time of 75 ns and supports non-repetitive avalanche energy up to 30 mJ. Housed in a low-profile SMPC (TO-277A) package, it withstands operating junction temperatures up to 175 °C.

Feature Summary

• Ultrafast reverse recovery characteristics for high-speed switching applications
• Controlled avalanche capability supporting non-repetitive surge energy
• Glass passivated junction ensuring stable leakage performance
• Low profile design optimized for automated placement processes

Applications

• Fast switching rectification in power supplies

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to confirm compliance requirements. Ensure the selected variant matches the required qualification level, such as commercial grade or AEC-Q101 automotive standards. Confirm package dimensions and terminal plating specifications align with PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high-voltage blocking capabilities combined with rapid turn-off speeds. The avalanche rating provides robustness against inductive load transients. Evaluate thermal resistance parameters relative to the intended PCB copper pad area to ensure safe operation within the specified temperature range under continuous load conditions.

Part Context

This device belongs to the AU2PK/AU2PM family of ultrafast rectifiers manufactured by Vishay General Semiconductor. It utilizes Trench MOS technology to achieve low forward voltage drop while maintaining high reliability. The eSMP series designation indicates a standardized surface-mount form factor designed for efficient integration into modern electronic assemblies.

Replacement Considerations

Direct substitutes include the AU2PK-M3/86A variant, which shares identical mechanical and electrical characteristics except for a reduced maximum repetitive peak reverse voltage rating of 800 V instead of 1000 V.
