November 2001IRFP254B250V N-Channel MOSFETGeneral Description FeaturesThese N-Channel enhancement mode power field effect 25A, 250V, RDS(on) = 0.14 @VGS = 10 Vtransistors are produced using Fairchilds proprietary, Low gate charge ( typical 95 nC)planar, DMOS technology. Low Crss ( typical 60 pF)This advanced technology has been especially tailored to Fast switchingminimize on-state resistance, provide superior switching 100% avalanche testedperformance, and withstand high energy pulse in the Improved dv/dt capabilityavalanche and commutation mode. These devices are wellsuited for high efficiency switching DC/DC converters andswitch mode power supplies.DG
