DESCRIPTION
The FDmeshTM associates all advantages of reduced
on-resistance and fast switching with an intrinsic fast-
recovery body diode. It is therefore strongly recom-
mended for bridge topologies, in particular ZVS phase-                  INTERNAL SCHEMATIC DIAGRAM
shift converters.

APPLICATIONS
s ZVS PHASE-SHIFT FULL BRIDGE CONVERTERS

  FOR SMPS AND WELDING EQUIPMENT
