The BUK7M45-40EX is a standard-level N-channel MOSFET from Nexperia USA, built with TrenchMOS technology. It is rated for a maximum drain-source voltage of 40V and a continuous drain current of 19A at 25°C case temperature, with a peak pulsed drain current of 77A. The device is qualified to AEC Q101, making it suitable for automotive applications.
The MOSFET has a maximum drain-source on-state resistance of 45mΩ at 10V gate drive and 5A drain current, with a typical on-resistance of 33mΩ. Maximum gate charge is 6.2nC at 10V, and input capacitance is 317pF at 25V drain-source voltage. Gate threshold voltage is 4V maximum at 1mA, and the gate-source voltage range is ±20V.
The device comes in an LFPAK33 (SOT1210) surface-mount package with 8 leads and a mounting base connected to the drain. It dissipates up to 31W at 25°C case temperature and operates over a junction temperature range of -55°C to 175°C.
Typical applications include 12V automotive systems, motor, lamp and solenoid control, transmission control, and high-performance power switching circuits.
