2SK3018

hongjiacheng · MOSFETs · SOT-23

2SK3018 from hongjiacheng, 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 terminal, protected by a built-in gate protection diode, with VGS rated ±20 V and gate threshold VGS(th) of 0.8 to 1.5 V at VDS=3.0 V, ID=0.1 mA.
2 S passive Source terminal of the N-channel MOSFET; the datasheet gives no separate pin-level limit for this terminal beyond the device ratings.
3 D passive Drain terminal, rated for VDS of 30 V, continuous drain current ID of 0.1 A and pulsed drain current IDM of 0.4 A.
