TX20N03

XDS · MOSFETs · TO-252

TX20N03 from XDS, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate; gate-source voltage limited to ±20 V, with threshold VGS(th) of 1.2 V min to 2.5 V max at ID=250uA.
2 D passive Drain, also connected to the exposed tab; drain-source voltage 30 V max and continuous drain current 20 A at TC=25℃.
3 S passive Source; continuous source current 20 A max and pulsed source current 60 A max through the body diode.
