ID
45 A
■ 100% avalanche tested
■ High dv/dt and avalanche capabilities
■ Low input capacitance and gate charge
■ Low gate input resistance
Application
■ Switching applications
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.
