KSI2302W

KUU · MOSFETs · SOT-323

KSI2302W from KUU, in a SOT-323. 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, labelled "Base" on the datasheet package drawing; gate-source voltage limit is ±8 V and threshold is 0.65 to 1.2 V (0.95 V typ) at ID=50µA.
2 S passive Source, labelled "Emitter" on the datasheet package drawing; continuous source-drain diode current is 0.6 A max.
3 D passive Drain, labelled "Collector" on the datasheet package drawing; drain-source voltage is 20 V max and continuous drain current is 2.1 A.
