BUK7Y3R5-40E,115

Overview

The BUK7Y3R5-40E is a standard level N-channel MOSFET utilizing TrenchMOS technology, housed in an LFPAK56 (Power SO8) package. It features a drain-source voltage of 40 V and a maximum continuous drain current of 100 A at a mounting base temperature of 25 °C. The device exhibits a typical on-state resistance of 3.5 mΩ at 25 °C and supports a total power dissipation of 167 W under specified conditions. It operates within a junction temperature range of -55 °C to +175 °C and includes repetitive avalanche rating capabilities.

Feature Summary

Qualified to the AEC-Q101 automotive standard for high-performance applications.
Features a true standard level gate with a threshold voltage greater than 1 V at 175 °C.
Designed for thermally demanding environments with a 175 °C operating rating.
Includes repetitive avalanche rating for robust operation.

Applications

12 V Automotive systems
Motors, lamps and solenoid control
Transmission control
Ultra high performance power switching

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel or cut tape specifications. Ensure the component meets the required AEC-Q101 qualification status for your target application. Cross-reference the marking code '73E540' with the datasheet to authenticate the part number during incoming inspection.

Selection Notes

Select this component when a standard level gate drive is required alongside high current handling in a compact surface-mount footprint. The LFPAK56 package offers improved thermal performance compared to traditional wire-bond packages. Consider the 175 °C junction temperature rating for designs operating in elevated ambient temperatures without excessive derating.

Part Context

This device belongs to the Nexperia BUK7Y series of N-channel MOSFETs. It utilizes TrenchMOS technology to achieve low on-state resistance within the LFPAK56 package. The series is specifically engineered to meet automotive reliability standards while providing efficient power switching capabilities for 12 V systems.

Replacement Considerations

Consult the Nexperia product selector tool for direct replacements with identical electrical characteristics and pinout configurations. Verify that any substitute component maintains the same AEC-Q101 qualification and LFPAK56 package dimensions to ensure mechanical compatibility.
