www.DataSheet4U.com STB85NF3LL N-channel 30V - 0.006Ω - 85A - D2PAK Low gate charge STripFET™ II Power MOSFET General features Type STB85NF3LL ■ ■ ■ VDSS 30V RDS(on) <0.008Ω ID 85A 3 1 Optimal RDS(on) x Qg trade-OFF @4.5V COnduction losses reduced Switching losses reduced D²PAK Description This application specific Power MOSFET is the third genaration 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.
