STD40NF03L N-channel 30V - 0.0090 - 40A - DPAK Low gate charge STripFET II Power MOSFET General features Type V R I DSS DS(on) D STD40NF03L 30V <0.011 40A Logic level device 3 Optimal R x Q trade-off DS(on) g 1 Conduction losses reduced DPAK Switching losses reduced Low threshold drive Description This application specific Power MOSFET is the third generation of STMicroelectronics unique Internal schematic diagramSingle Feature Siz strip-based process. The resulting transistor shows the best trade-off between on-resistance and gate charge. When used as high and low side in buck regulators, it gives the best performance in terms of both conduction and switching losses. This is extremely important for motherboards where fast switching and high efficiency are of paramount importance.
