STW20NM50FD
N-CHANNEL 500V - 0.22 - 20A TO-247
FDmeshTM Power MOSFET (with FAST DIODE)

TYPE VDSS RDS(on) ID

STW20NM50FD 500V <0.25 20 A
s TYPICAL RDS(on) = 0.22
s HIGH dv/dt AND AVALANCHE CAPABILITIES
s 100% AVALANCHE TESTED

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
