January 2015FDMS0309ASN-Channel PowerTrench SyncFETTM30 V, 49 A, 3.5 mFeatures General DescriptionThe FDMS0309AS has been designed to minimize losses in Max rDS(on) = 3.5 m at VGS = 10 V, ID = 21 Apower conversion application. Advancements in both silicon and Max rDS(on) = 4.3 m at VGS = 4.5 V, ID = 19 Apackage technologies have been combined to offer the lowest rDS(on) while maintaining excellent switching performance.This Advanced package and silicon combination for low rDS(on) anddevice has the added benefit of an efficient monolithic Schottky high efficiencybody diode.
