www.DataSheet4U.com STS8DNF3LL Dual N-channel 30V - 0.017Ω - 8A SO-8 Low gate charge STripFET™ II Power MOSFET General features Type STS8DNF3LL ■ ■ ■ VDSS 30V RDS(on) <0.020Ω ID 8A Optimal RDS(on) x Qg trade-off @ 4.5V Conduction losses reduced Switching losses reduced S0-8 Description This application specific Power MOSFET is the second 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.
