Cmos · MOSFETs · TO-220

CMP8972 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; absolute maximum gate-source voltage is ±8 V, with threshold voltage of 0.5 V to 1.5 V at ID=250 uA.
2 D passive Drain (also the tab); drain-source voltage rated 20 V, continuous drain current 80 A at TC=25°C and pulsed 320 A.
3 S passive Source; continuous body-diode source current is 80 A and pulsed source current is 320 A.
