BUK7K8R7-40EX Description

Short technical summary and product information.

The BUK7K8R7-40EX is a dual N-channel standard level MOSFET from Nexperia, designed for high-performance automotive and industrial applications. It features a drain-source voltage rating of 40V and a continuous drain current of 30A at 25°C. The device offers a low typical on-resistance of 7mΩ (maximum 8.5mΩ) at VGS=10V, ensuring efficient power switching.

 

This MOSFET is qualified to AEC-Q101 standard, making it suitable for automotive environments. It is rated for operation up to 175°C junction temperature and includes repetitive avalanche capability. The gate threshold voltage is 4V maximum, and the device has a total gate charge of 21.8nC typical.

 

The BUK7K8R7-40EX is housed in the LFPAK56D (SOT-1205) surface-mount package, which provides excellent thermal performance with a power dissipation of 53W at 25°C case temperature. The dual MOSFET configuration integrates two independent N-channel FETs in a single package, saving board space.

 

Typical applications include 12V automotive systems, motor control, lamp and solenoid control, transmission control, and general high-performance power switching.
