STD40NF03L

STD40NF03L N-channel 30V - 0.0090Ω - 40A - DPAK Low gate charge STripFET™ II Power MOSFET General features www.DataSheet4U.com Type VDSS 30V RDS(on) <0.011Ω ID 40A STD40NF03L ■ ■ ■ ■ ■ Logic level device Optimal RDS(on) x Qg trade-off Conduction losses reduced Switching losses reduced Low threshold drive DPAK 3 1 Description This application specific Power MOSFET is the third generation of STMicroelectronics unique "Single Feature Size™" 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.
