STF12NM50N, STP12NM50N
N-channel 500 V, 0.29 Ω, 11 A MDmesh™ II Power MOSFET
TO-220 - DPAK - D2PAK - I 2PAK - TO-220FP
Features
■100% avalanche tested
■Low input capacitance and gate charge
■Low gate input resistance
Application
■Switching applications
Description
This series of devices is realized with the second
generation of MDmesh™ technology. This
revolutionary Power MOSFET associates a new
vertical structure to the company’s strip layout to
yield one of the world’s lowest on-resistance and
gate charge. It is therefore suitable for the most
demanding high efficiency converters.
