1N6940UTK3AS

Overview

The Microchip Technology 1N6940UTK3AS is a silicon Schottky rectifier diode designed for high-current applications. It features a maximum DC reverse voltage (Vr) of 15 V and an average rectified forward current (Io) of 150 A. The device utilizes a surface-mount technology package, specifically the UTK-3 configuration, to facilitate automated assembly and robust thermal performance in power supply circuits.

Feature Summary

• Schottky barrier construction for low forward voltage drop
• High current handling capability up to 150 A
• Surface-mount packaging for efficient board space utilization

Applications

• High-current DC-DC converters
• Power supply output rectification
• Free-wheeling diodes in motor drive circuits

Procurement Notes

Verify the specific suffix 'AS' against the manufacturer's official datasheet to confirm exact mechanical dimensions and marking codes. Ensure compatibility with peak reverse voltage requirements in the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a low forward voltage drop is critical for efficiency at high currents. The 15 V rating suits low-voltage output stages. Confirm that the thermal management solution supports the 150 A continuous current rating under expected operating ambient temperatures.

Part Context

This part belongs to the Microchip (formerly Microsemi) 1N69xx series of high-power Schottky rectifiers. These components are engineered for ruggedness and reliability in industrial and automotive environments where high surge current capacity and fast switching characteristics are required.

Replacement Considerations

Check for direct cross-reference part numbers from Microchip or authorized distributors. Verify that any substitute maintains the 150 A current rating, 15 V reverse voltage, and compatible UTK-3 footprint to ensure mechanical and electrical interchangeability.
