AR4PD-M3/86A

Overview

The AR4PD-M3/86A is a surface-mount Avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 2 A. The component utilizes the TO-277A (SMPC) package, designed for compact circuit board layouts. It operates within a junction temperature range of -55°C to 175°C.

Feature Summary

• Incorporates avalanche ruggedness characteristics for enhanced reliability under transient stress conditions.

Applications

• General-purpose circuit protection
• Surge suppression in low-voltage DC lines

Procurement Notes

Verify the specific datasheet revision and electrical parameters directly with the manufacturer or authorized distributors before integration. Confirm that the TO-277A footprint matches your PCB design requirements. Ensure compliance with RoHS standards as indicated by the M3 suffix. Cross-reference part numbers to avoid confusion with similar Vishay diode series.

Selection Notes

Select this component when a robust, surface-mount solution is required for protecting circuits against voltage spikes up to 200 V. The 2 A current rating suits moderate power applications. Consider the TO-277A package size constraints and thermal management needs relative to the 175°C maximum junction temperature capability.

Part Context

This device belongs to Vishay's general-purpose diode portfolio, specifically engineered for surface-mount technology. The TO-277A package offers a small form factor suitable for high-density electronics. As an avalanche-rated diode, it provides specific protection capabilities distinct from standard rectifiers or Zener diodes within the same product family.

Replacement Considerations

Consult official substitution guides for equivalent avalanche diodes in the TO-277A package with matching 200 V and 2 A ratings. Verify pinout compatibility and thermal performance before replacing.
