STB12NM50FD - STB12NM50FD-1
STP12NM50FD/FP - STW14NM50FD
N-channel 500V - 0.32Ω - 12A - TO-220/FP - D2/I2PAK - TO-247
FDmesh™ Power MOSFET (with fast diode)
General features
■100% avalanche tested
■High dv/dt and avalanche capabilities
■Low input capacitance and gate charge
■Low gate input resistance
■Tight process control and high manufacturing
yields
Description
The FDmesh™ associates all advantages of
reduced on-resistance and fast switching with an
intrinsic fast-recovery body diode. It is therefore
strongly recommended for bridge topologies, in
particular ZVS phase-shift converters.
Applications
