SI2319 from HXY MOSFET, 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, with a maximum gate-source voltage of ±20 V and a threshold of -1.0 V to -3.0 V at ID=-250 µA. |
| 2 | S | passive | Source of the P-channel MOSFET; the body diode forward current IS is rated -3.3 A. |
| 3 | D | passive | Drain of the P-channel MOSFET, rated for VDS of -40 V and continuous ID of -5 A (pulsed -18 A). |
