The BUK9Y29-40E,115 is a logic-level N-channel MOSFET from Nexperia, designed and qualified to AEC Q101 standard for automotive applications. It uses TrenchMOS technology to achieve a low on-resistance of 29 mΩ maximum at 5V gate drive and 5A drain current. The device can handle a continuous drain current of 25A at 25°C case temperature, with a peak pulsed drain current of 101A.
This MOSFET operates over a junction temperature range of -55°C to 175°C, making it suitable for thermally demanding environments. The gate threshold voltage is 2.1V maximum at 1mA drain current, ensuring true logic-level switching. Typical gate charge is 5 nC at 5V, enabling efficient high-frequency switching.
Packaged in the LFPAK56 (SOT-669) surface-mount package, also known as Power-SO8, the device has 4 leads and a gull-wing termination style. The mounting base is connected to the drain for effective heat dissipation. This package is designed for compact power applications.
With its 40V drain-source voltage rating and AEC Q101 qualification, the BUK9Y29-40E is well-suited for 12V automotive systems including motor control, lamp and solenoid drivers, and transmission control. It is also suitable for high-performance power switching applications.
