Nexperia BUK6Q12-40PJ MOSFET

Nexperia BUK6Q12-40PJ MOSFET is a 40V, automotive, P-channel FET in an MLPAK33 (SOT8002-3) SMD plastic package using Trench MOSFET technology. This MOSFET is logic-level compatible and features side-wettable flanks for optical solder inspection. The BUK6Q12-40PJ MOSFET operates in negative mode during normal operation, with drain-source voltage (VDS). The current flows when a negative voltage is applied to the gate relative to the source (VGS). The maximum voltage that can be safely applied between the drain and source terminals is 40V. This MOSFET is offered in a thermally efficient package in a small form factor (3.3mm x 3.3mm footprint). The BUK6Q12-40PJ MOSFET is AEC-Q101 qualified. This MOSFET is ideal for reverse polarity protection, high-speed line drivers, high-side load switches, and relay drivers.
