The BUK9Y21-40E is an N-channel logic level MOSFET from Nexperia, designed for 12V automotive systems and high performance power switching applications. It features a drain-source voltage rating of 40V and a continuous drain current of 33A at 25°C case temperature, with a maximum on-state resistance of 17mOhm at 10V gate drive.
This MOSFET uses TrenchMOS technology and is housed in the LFPAK56 (Power-SO8) surface mount package with 4 leads. It is qualified to AEC Q101 standard and is repetitive avalanche rated, making it suitable for demanding automotive environments. The device supports true logic level gate drive with a threshold voltage of 2.1V maximum.
The part offers a maximum power dissipation of 45W at 25°C and an operating junction temperature range of -55°C to 175°C. Key dynamic characteristics include an input capacitance of 824pF and a typical gate-drain charge of 2.7nC, enabling efficient switching performance.
