Ω, 45 A, TO-247

FDmesh™ Power MOSFET (with fast diode)

Features

Application

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.
