AU2PM-M3/87A

Overview

The AU2PM-M3/87A is an ultrafast avalanche surface mount rectifier from Vishay General Semiconductor, featuring a single circuit configuration in the SMPC (TO-277A) package. It supports a maximum repetitive peak reverse voltage of 1000 V and a DC forward current of 2.0 A. Key electrical parameters include a typical instantaneous forward voltage of 1.42 V at 2.0 A, a maximum reverse recovery time of 75 ns, and a peak forward surge current capability of 30 A. The device operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

• Glass passivated pellet chip junction for enhanced reliability
• Controlled avalanche characteristics with high forward surge capability
• Very low profile design suitable for automated placement
• Meets MSL level 1 per J-STD-020 with LF maximum peak of 260 °C

Applications

• Fast switching rectification of power supplies
• Inverters and converters
• Freewheeling diodes for consumer, automotive, and telecommunication equipment
• Lighting applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the delivery mode and base quantity. The /87A suffix indicates a 6500-unit base quantity delivered in a 13-inch diameter plastic tape and reel. Confirm that the component meets the required material categorization and compliance standards for your specific manufacturing process before finalizing procurement.

Selection Notes

Select this component when a high-voltage rating of 1000 V is required alongside fast reverse recovery characteristics. The controlled avalanche capability makes it suitable for applications involving inductive load switching. Ensure the thermal management design accommodates the specified thermal resistance values and that the operating environment remains within the -55 °C to +175 °C junction temperature limits.

Part Context

This part belongs to the eSMP Series, which utilizes the SMPC (TO-277A) surface mount package. The series includes variants such as the AU2PK and AU2PM, differentiated primarily by their maximum repetitive peak reverse voltage ratings. The M3 suffix denotes halogen-free, RoHS-compliant commercial grade construction, while HM3 variants are available for AEC-Q101 qualified automotive requirements.

Replacement Considerations

Direct substitutes within the same family include the AU2PK-M3/87A, which shares identical physical dimensions and electrical characteristics except for a reduced maximum repetitive peak reverse voltage of 800 V. Verify that the lower voltage rating of the alternative part is sufficient for the target application circuit.
