CMP18N20

Cmos · MOSFETs · TO-220

CMP18N20 from Cmos, in a TO-220. 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 ±30 V, with gate threshold of 2 V to 4 V at ID=250uA.
2 D passive Drain; 200 V drain-source voltage, 18 A continuous drain current at TC=25℃ and 72 A pulsed.
3 S passive Source; continuous source current 18 A and 72 A pulsed through the body diode.
