SI2318DS from TECH PUBLIC, 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 limit is ±20 V, with threshold VGS(TH) of 1 V min to 3 V max at ID = 250 µA. |
| 2 | S | passive | Source of the N-channel MOSFET; carries continuous drain current up to 3.9 A (16 A pulsed) and is the anode of the body diode. |
| 3 | D | passive | Drain of the N-channel MOSFET; drain-source voltage rated 40 V, RDS(on) 45 mΩ max at VGS = 10 V and 62.5 mΩ max at VGS = 4.5 V. |
