SP2101CT3 from Siliup, in a SOT-323. 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 P-channel MOSFET; gate-source voltage limited to ±12 V absolute maximum, threshold -0.5 to -1.0 V at ID=-250µA. |
| 2 | S | passive | Source of the P-channel MOSFET; body diode forward voltage up to -1.2 V at IS=-1A. |
| 3 | D | passive | Drain of the P-channel MOSFET; drain-source voltage -20 V maximum and continuous drain current -1.2 A. |
