STB20NM50FD STF20NM50FD - STP20NM50FD N-channel 500 V, 0.22 Ω, 20 A D2PAK, TO-220FP, TO-220 FDmesh™ Power MOSFET (with fast diode) Features Type VDSS RDS(on) max RDS(on)* Qg ID STB20NM50FD 500 V < 0.25 Ω 8.36 Ω* nC STF20NM50FD 500 V < 0.25 Ω 8.36 Ω* nC STP20NM50FD 500 V < 0.25 Ω 8.36 Ω* nC 20 A 20 A 20 A ■ High dv/dt and avalanche capabilities ■ 100% avalanche tested ■ Low input capacitance and gate charge ■ Low gate input resistance ■ Tight process control and high manufacturing yields 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-220FP 3 1 D²PAK 3 2 1 TO-220 Figure 1. Internal schematic diagram Table 1.
