http://www.ncepower.com NCEP40T11NCE N-Channel Super Trench Power MOSFET Description The NCEP40T11 uses Super Trench technology that is uniquely optimized to provide the most efficient high frequency switching performance. Both conduction and switching power losses are minimized due to an extremely low combination of RDS(ON) and Qg. This device is ideal for high-frequency switching and synchronous rectification. General Features Schematic Diagram VDS =40V,ID =110A RDS(ON)=2.9m (typical) @ VGS=10V RDS(ON)=4.4m (typical) @ VGS=4.5V Excellent gate charge x RDS(on) product(FOM) Very low on-resistance RDS(on) 150 C operating temperature Pb-free lead plating Marking and pin assignment 100% UIS tested Application DC/DC Converter Ideal for high-frequency switching and synchronous rectification 100% UIS
