SI2333AI-MS from MSKSEMI, 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 P-channel MOSFET; gate-source voltage limit is ±12 V and VGS(th) is -0.45 to -1.0 V at ID=-250μA. |
| 2 | S | passive | Source of the P-channel MOSFET; the body diode forward current is limited to 1.6 A. |
| 3 | D | passive | Drain of the P-channel MOSFET; VDS is -18 V maximum, continuous ID is -6.5 A and pulsed IDM is -15 A. |
