Description Figure 1. Internal schematic diagram

FDmeshTM technology combines the MDmeshTM
features with an intrinsic fast-recovery body
diode. The resulting product has reduced on-
resistance and fast switching commutations,
making it especially suitable for bridge topologies
where low trr is required.
