SK2309AA

Shikues · MOSFETs · SOT-23

SK2309AA from Shikues, 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 is limited to ±20 V, with a threshold of -1.0 to -2.5 V at ID=-250μA.
2 S passive Source; body-diode continuous current is -2.0 A and the drain current rating is -2.0 A at TA=25℃.
3 D passive Drain; drain-source voltage is rated -60 V, with pulsed drain current of -9 A and RDS(ON) under 300 mΩ at VGS=-10 V.
