KI2302DS

KEXIN · MOSFETs · SOT-23

KI2302DS from KEXIN, 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 Gate input Gate of the N-channel MOSFET; the datasheet gives a gate-source voltage limit of VGS ±8 V.
2 Source passive Source of the N-channel MOSFET; the datasheet gives a drain-source voltage rating of VDS 20 V.
3 Drain passive Drain of the N-channel MOSFET; the datasheet gives a continuous drain current of 2.1 A at Ta = 25 and a pulsed drain current IDM of 10 A.
