BUK7K6R2-40EX Description

Short technical summary and product information.

The BUK7K6R2-40EX is a dual N-channel standard level MOSFET from Nexperia, built with TrenchMOS technology and housed in a compact LFPAK56D (Dual Power-SO8) surface-mount package. It offers a drain-source voltage rating of 40 V, a continuous drain current of 40 A (limited by package), and a maximum on-state resistance of 5.8 mΩ at 10 V gate drive (typical 4.8 mΩ). The device is designed and qualified to AEC Q101, making it suitable for demanding automotive applications. With a wide operating junction temperature range of -55 °C to 175 °C, it can handle thermally stressful environments. The MOSFET provides a total power dissipation of 68 W at 25 °C case temperature and is repetitive avalanche rated. Typical applications include 12 V automotive systems, motor control, lamp and solenoid drivers, transmission control, and high-performance power switching. The dual configuration saves board space and simplifies layout in circuits requiring two independent N-channel switches.
