The BUK9K25-40EX from Nexperia is a dual N-channel logic level MOSFET designed for high-performance power switching applications. It features a maximum drain-source voltage of 40V and a continuous drain current of 18.2A at 25°C. The device offers a typical on-state resistance of 24 mΩ at VGS = 5V, making it suitable for efficient power management.
This MOSFET utilizes TrenchMOS technology and is qualified to the AEC Q101 standard for automotive applications. It is rated for operation at junction temperatures up to 175°C, enabling use in thermally demanding environments. The logic level gate allows direct drive from low-voltage logic circuits.
The BUK9K25-40EX is supplied in the LFPAK56D (SOT1205) surface mount package, which provides a compact footprint for space-constrained designs. Typical applications include 12V automotive systems, motor control, lamp and solenoid drivers, and transmission control units.
