AR1PD-M3/84A

Overview

The AR1PD-M3/84A is a silicon avalanche rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a single diode configuration housed in a surface-mount DO-220AA (SMP) package with two pins. The device is rated for a maximum DC reverse voltage of 200V and an average forward current of 1A. Key electrical parameters include a maximum forward voltage drop of 1.6V at specified conditions and a junction temperature range from -55°C to +175°C. The component dimensions are 3.61mm in length, 2.18mm in width, and 1.15mm in height.

Feature Summary

• Incorporates avalanche ruggedness characteristics for enhanced reliability under transient conditions
• Utilizes glass passivation to protect the junction against mechanical stress
• Designed for high-temperature operation suitable for demanding environments

Applications

• High-voltage rectification circuits requiring avalanche capability
• Flyback diodes in inductive load switching applications
• Protection circuits against voltage spikes in power supplies

Procurement Notes

Verify the specific suffix 'M3' confirms RoHS compliance and halogen-free status as per manufacturer specifications. Confirm the '84A' packaging designation matches the required reel or tape-and-reel quantity for your assembly line. Ensure the DO-220AA footprint aligns with your PCB design guidelines before finalizing procurement orders.

Selection Notes

Select this component when an avalanche-rated silicon rectifier is required in a compact surface-mount form factor. The 200V rating makes it suitable for low-to-medium voltage AC-DC conversion stages. Consider the thermal management requirements given the 1A current rating and the thermal resistance inherent to the DO-220AA package for your specific circuit layout.

Part Context

This part belongs to Vishay's general-purpose avalanche rectifier series designed for surface-mount applications. It shares the DO-220AA footprint with other Vishay diodes but is distinguished by its avalanche energy rating. The M3 suffix indicates lead-free construction compliant with modern environmental directives, differentiating it from older non-compliant variants in the same voltage class.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and avalanche energy ratings if considering alternative manufacturers.
