Final Datasheet FDFS6N754 Integrated N-Channel PowerTrench® MOSFET and Schottky Diode August 2006 FDFS6N754 Integrated N-Channel 30V, 4A, 56mΩ Features PowerTrench® tm MOSFET and Schottky Diode General Description The FDFS6N754 combines the exceptional performance of Fairchild's PowerTrench MOSFET technology with a very low forward voltage drop Schottky barrier rectifier in an SO8 package. This device is designed specifically as a single package solution for DC to DC converters. It features a fast switching, low gate charge MOSFET with very low on-state resistance. The independently connected Schottky diode allows its use in a variety of DC/DC converter topologies.
