Internal schematic diagram Description FDmesh technology combines the MDmesh 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 t is required. rr 3 - V Table 1.
