STW45NM50FD

STW45NM50FD N-channel 500 V, 0.07 Ω, 45 A, TO-247 FDmesh™ Power MOSFET (with fast diode) Features Type STW45NM50FD VDSS 500 V RDS(on) max < 0.1 Ω 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. 3 2 1 TO-247 Figure 1. Internal schematic diagram $ ' Table 1.
