KIA Semicon Tech · MOSFETs · SOT-23

KIA2301 from KIA Semicon Tech, 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 terminal; gate-source voltage limited to ±8 V maximum, with threshold of -0.5 to -1.0 V at ID=-250µA.
2 Source passive Source terminal; continuous source current (diode conduction) is limited to -1.6 A.
3 Drain passive Drain terminal; drain-source voltage rated -20 V and continuous drain current -2.8 A at TA=25°C.
