August 2010FDMS0308CSN-Channel PowerTrench SyncFETTM 30 V, 42 A, 3 m Features General DescriptionThe FDMS0308CS has been designed to minimize losses in Max rDS(on) = 3.0 m at VGS = 10 V, ID = 21 Apower conversion application. Advancements in both silicon and Max rDS(on) = 3.5 m at VGS = 4.5 V, ID = 17 Apackage technologies have been combined to offer the lowest Advanced Package and Silicon combination for low rDS(on) rDS(on) while maintaining excellent switching performance. This device has the added benefit of an efficient monolithic Schottky and high efficiency body diode.
