November 2001IRFR220B / IRFU220B200V N-Channel MOSFETGeneral Description FeaturesThese N-Channel enhancement mode power field effect 4.6A, 200V, RDS(on) = 0.8 @VGS = 10 Vtransistors are produced using Fairchilds proprietary, Low gate charge ( typical 12 nC)planar, DMOS technology. Low Crss ( typical 10 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,switch mode power supplies, DC-AC converters foruninterrupted power supply and motor control.DD
