AU2PK-M3/87A

Overview

The AU2PK-M3/87A is a dual common cathode Schottky barrier rectifier manufactured by Vishay General Semiconductor. It features two independent diodes within a single SOD-128FL package, designed for surface-mount applications. The device offers low forward voltage drop and high switching efficiency, making it suitable for DC-DC converters and power supply circuits. Key electrical characteristics include a maximum repetitive peak reverse voltage of 40V and an average forward rectified current of 2A per diode at specified temperatures.

Feature Summary

• Dual common cathode configuration in a compact surface-mount package
• Low forward voltage drop for improved energy efficiency
• High surge current capability for robust operation
• Halogen-free and RoHS compliant construction

Applications

• DC-DC converter output rectification
• Free-wheeling diodes in synchronous rectifiers
• Power supply input protection circuits
• Reverse polarity protection in portable devices

Procurement Notes

Verify the specific suffix /87A corresponds to the required tape and reel packaging quantity as defined in the official datasheet. Confirm that the M3 suffix indicates lead-free termination and halogen-free material compliance. Ensure the ordering part number matches the exact package outline and marking code provided in the manufacturer's documentation to avoid substitution errors.

Selection Notes

Select this component when a dual Schottky rectifier with a 40V rating and 2A current capacity is required in a small footprint. Consider the thermal resistance and junction temperature limits under expected load conditions. Verify that the SOD-128FL package dimensions fit the PCB layout constraints. Compare forward voltage specifications against system efficiency requirements to ensure optimal performance.

Part Context

This component belongs to Vishay's AU series of Schottky barrier rectifiers, which are optimized for high-frequency switching applications. The series utilizes advanced silicon technology to achieve low leakage current and fast recovery times. The AU2PK variant specifically integrates two diodes to save board space compared to discrete solutions.

Replacement Considerations

Check for direct substitutes such as other dual Schottky diodes in SOD-128 packages with matching 40V and 2A ratings. Verify pinout compatibility and thermal characteristics before substituting. Ensure any replacement part meets the same RoHS and halogen-free standards if required by the design.
