Pb Free Producthttp://www.ncepower.com NCEP40T17GNCE N-Channel Super Trench Power MOSFET Description The NCEP40T17G 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.
