http://www.ncepower.com NCEP40T12GUNCE N-Channel Super Trench Power MOSFET General Features Description VDS =40V,ID =120A The NCEP40T12GU uses Super Trench technology that is RDS(ON)=2.05m (typical) @ VGS=10V uniquely optimized to provide the most efficient high RDS(ON)=3.1m (typical) @ VGS=4.5V frequency switching performance. Both conduction and Excellent gate charge x RDS(on) product(FOM) switching power losses are minimized due to an extremely low Very low on-resistance RDS(on) combination of RDS(ON) and Qg. This device is ideal for 150 C operating temperature high-frequency switching and synchronous rectification.
