KY2004K from KY, 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 limited to ±10 V, with threshold VGS(th) of -0.35 V min to -1 V max at ID = -250 µA. |
| 2 | S | passive | Source of the P-channel MOSFET; continuous drain current is -0.66 A and pulsed drain current -1.2 A. |
| 3 | D | passive | Drain; drain-source voltage rated -20 V, with RDS(on) of 380 mΩ typ. (520 mΩ max) at VGS = -4.5 V. |
