SI2301M-6AF from FOSAN, 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 is limited to ±12 V and the gate threshold voltage is -0.4 V min to -1.0 V max at ID = -250 uA. |
| 2 | S | passive | Source of the P-channel MOSFET, with the body diode (VSD max -1.2 V at ISD = -3 A) running from drain to source. |
| 3 | D | passive | Drain; drain-source voltage is rated -20 V, continuous drain current -3 A and pulsed drain current -11 A. |
