http://www.ncepower.comNCEP40T11KNCE N-Channel Super Trench Power MOSFETDescriptionThe NCEP40T11K uses Super Trench technology that isuniquely optimized to provide the most efficient highfrequency switching performance. Both conduction andswitching power losses are minimized due to an extremelylow combination of R and Q . This device is ideal forDS(ON) ghigh-frequency switching and synchronous rectification.Schematic DiagramGeneral Features V =40V,I =110ADS DR =2.4m (typical) @ V =10VDS(ON) GSR =3.3m (typical) @ V =4.5VDS(ON) GS Excellent gate charge x R product(FOM)DS(on) Very low on-resistance RDS(on) 175 C operating temperature Pb-free lead plating 100% UIS testedMarking and pin assignmentApplication DC/DC Converter Ideal for high-frequency switching and synchronousrectification100% UIS TEST
