BUK7M6R3-40EX

Overview

The Nexperia BUK7M6R3-40EX is a standard level N-channel MOSFET utilizing TrenchMOS technology, housed in an LFPAK33 (SOT1210) package. It features a drain-source voltage of 40 V and a maximum on-state resistance of 6.3 mΩ at 25 °C. The device supports a continuous drain current of 70 A and dissipates up to 79 W. Qualified to the AEC-Q101 automotive standard, it operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

Qualified to the AEC-Q101 automotive reliability standard for high-performance applications.
Rated for repetitive avalanche energy operation to withstand transient electrical stress.
Maintains true standard level gate functionality with a threshold voltage exceeding 1 V at elevated temperatures.

Applications

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

Procurement Notes

Verify the specific suffix 'EX' against the manufacturer's official ordering information to confirm packaging details such as reel specifications or tape-and-reel dimensions. Confirm that the requested component matches the LFPAK33 package outline SOT1210. Ensure compliance with RoHS directives and REACH regulations relevant to your region before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring low conduction losses in a compact surface-mount footprint. The 6.3 mΩ on-resistance makes it suitable for high-current switching tasks. Verify that the thermal management design accommodates the specified power dissipation limits and that the gate drive voltage aligns with the standard level gate requirements for optimal performance.

Part Context

This part belongs to the BUK7M series of N-channel MOSFETs from Nexperia. These devices are engineered using TrenchMOS technology to deliver enhanced performance in automotive environments. The LFPAK33 package provides efficient thermal transfer through a dedicated mounting base connected to the drain terminal.

Replacement Considerations

Consult the official Nexperia replacement guide for verified substitutes. Cross-reference pinouts, package dimensions, and electrical parameters to ensure compatibility without modifying the existing circuit layout or thermal design.
