BUK7S1R0-40HJ Description

Short technical summary and product information.

The BUK7S1R0-40HJ is an automotive N-channel MOSFET from Nexperia, designed using Trench 9 superjunction technology for low on-resistance and high efficiency. It is rated for a maximum drain-source voltage of 40V and a continuous drain current of 325A at Tmb=25°C, with a maximum power dissipation of 375W. The device features an ultra-low on-resistance of 1 mOhm max (0.62 mOhm typical) at VGS=10V, ID=25A, minimizing conduction losses. Gate charge is 137 nC max, and input capacitance is 10322 pF max, enabling efficient switching in high-frequency applications.

 

The MOSFET is qualified beyond AEC-Q101, ensuring reliability in harsh automotive environments. It operates over a junction temperature range of -55°C to 175°C, suitable for thermally demanding applications. The LFPAK88 package (SOT-1235) with copper clip and gull wing leads provides excellent thermal performance and board-level reliability, with visual solder joint inspection capability. Typical applications include 12V automotive systems, 48V DC/DC converters, high-power motor control, solenoid and lamp drivers, reverse polarity protection, and LED lighting.
