AU3PD-M3/87A

Overview

The AU3PD-M3/87A is a single avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 200 V and an average rectified current (Io) of 1.7 A. The component utilizes the TO-277A (SMPC) surface mount package. It operates within a junction temperature range of -65°C to 175°C.

Feature Summary

• Engineered with avalanche characteristics for robust energy handling capabilities
• Designed for surface mount integration using the TO-277A package format

Applications

• Circuit protection applications requiring avalanche rating
• Power supply input stages
• General purpose rectification in compact designs

Procurement Notes

Verify the specific suffix /87A against the manufacturer's latest documentation to confirm packaging configuration and compliance status. Ensure the ordering part number matches the required tape and reel specifications. Cross-reference the datasheet revision date to validate electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when a surface mount avalanche diode with a 200 V reverse voltage rating is required. The 1.7 A current capability suits moderate power applications. The TO-277A package facilitates automated assembly processes while providing adequate thermal performance for the specified operating temperature range.

Part Context

This device belongs to the AU3PD series of avalanche diodes from Vishay. It is distinct from standard rectifiers by its ability to withstand repetitive avalanche conditions. The M3 suffix indicates lead-free construction, aligning with modern environmental standards for electronic components.

Replacement Considerations

The AU3PD-M3/86A is a documented alternative variant within the same series. Verify pinout compatibility and specific avalanche energy ratings before substitution.
