AR3PD-M3/86A

Overview

The AR3PD-M3/86A is a surface-mount avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage of 200 V and an average rectified current rating of 1.8 A. The component utilizes the TO-277A (SMPC) package, designed for robust thermal performance in compact layouts. It operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Engineered with avalanche technology for controlled breakdown characteristics
• Utilizes TO-277A (SMPC) surface-mount packaging for efficient board space utilization
• Rated for high junction temperatures up to 150°C

Applications

• General-purpose circuit protection
• Surge suppression applications
• Transient voltage handling in low-voltage systems

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical tolerances and packaging variations. Ensure compatibility with automated pick-and-place equipment due to the TO-277A form factor. Confirm that the 200V rating aligns with system requirements before integration.

Selection Notes

Select this component when a surface-mount solution is required for avalanche-rated protection. The TO-277A package offers higher current capability compared to standard small-signal packages. Consider the 1.8A average current limit and 200V reverse voltage constraints during design validation.

Part Context

This part belongs to Vishay's discrete diode portfolio, specifically utilizing the eSMP or similar advanced surface-mount series. The TO-277A (SMPC) package is shared across various Vishay power diode families, providing a standardized footprint for designers integrating multiple device types on a single PCB layout.
