Pb Free Producthttp://www.ncepower.com NCEP40T17ATNCE N-Channel Super Trench Power MOSFET Description The NCEP40T17ATuses 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. Schematic Diagram General Features VDS =40V,ID =170A RDS(ON)=1.4m (typical) @ VGS=10V Excellent gate charge x RDS(on) product(FOM) Very low on-resistance RDS(on) 175C operating temperature Pb-free lead plating 100% UIS tested TO-247 top view Application DC/DC Converter 100% UIS TESTED! Ideal for high-frequency switching and synchronous rectification 100% Vds TESTED! P
