SI2301DS from TECH PUBLIC, in a SOT-23-3. 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; controls the P-channel MOSFET, with gate-source voltage limit of ±12 V and threshold VGS(th) of -0.4 V min to -1 V max at ID=-250µA. |
| 2 | S | passive | Source terminal of the P-channel MOSFET; the body diode conducts source-to-drain with continuous diode forward current of -3 A. |
| 3 | D | passive | Drain terminal; drain-source voltage rated at -20 V, continuous drain current -3 A and pulsed -10 A. |
