AR3PM-M3/86A

Overview

The AR3PM-M3/86A is a fast switching avalanche surface-mount rectifier manufactured by Vishay General Semiconductor. It features a single diode configuration in an SMPC (TO-277A) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 1000 V, a maximum DC forward current of 3.0 A, and a peak forward surge current of 50 A. The device exhibits a typical reverse recovery time of 120 ns and a maximum instantaneous forward voltage of 1.9 V at 3.0 A. It 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 for rugged operation
• Very low profile construction suitable for automated placement
• Meets JESD 201 class 2 whisker test requirements

Applications

• Fast switching rectification of power supplies
• Inverters and converters
• Freewheeling diodes for consumer electronics
• Automotive applications
• Telecommunication equipment

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm the delivery mode and base quantity. The /86A designation indicates a standard plastic tape and reel packaging format with a base quantity of 1500 units. Ensure compliance with RoHS directives and material categorization standards required for your manufacturing process before finalizing procurement orders.

Selection Notes

Select this component when high voltage blocking capability up to 1000 V is required alongside fast switching speeds. The controlled avalanche rating allows for energy absorption capabilities useful in inductive load switching scenarios. Consider the thermal resistance values and derating curves if operating near maximum current limits or elevated ambient temperatures.

Part Context

This part belongs to the eSMP series of surface-mount rectifiers designed for compact electronic designs. It utilizes the SMPC (TO-277A) case style, which provides a robust mechanical structure while maintaining a low profile. The M3 suffix denotes halogen-free, RoHS-compliant commercial grade materials, distinguishing it from the HM3 automotive qualified variants.

Replacement Considerations

The AR3PK variant serves as a direct functional substitute with an identical package and ratings, differing only in the maximum repetitive peak reverse voltage specification of 800 V compared to the 1000 V rating of the AR3PM.
