KY · MOSFETs · SOT-23
KY2302S 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 of the N-channel MOSFET; gate-source voltage is rated at ±10 V (VGS). |
| 2 | S | passive | Source of the N-channel MOSFET; the source-drain diode forward voltage is 1.2 V max at VGS=0 V and IS=1 A. |
| 3 | D | passive | Drain of the N-channel MOSFET; rated at 20 V drain-source voltage (VDS) and 2 A continuous drain current (ID). |
