KI2301

LGE · MOSFETs · SOT-23

KI2301 from LGE, in a SOT-23. 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 limit is ±12 V and the device operates with gate drive as low as 2.5 V (VGS(th) -0.4 to -1 V).
2 S passive Source of the P-channel MOSFET; continuous drain current is -3 A and diode forward current is -1.3 A.
3 D passive Drain of the P-channel MOSFET; drain-source voltage is -20 V, continuous current -3 A and pulsed current -10 A.
