SI2302S from FOSAN, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate; threshold voltage VGS(th) 0.5-1.5 V (ID=250 µA, VGS=VDS); gate-source voltage rating ±10 V; gate leakage IGSS ≤ 100 nA at VGS=+10 V. |
| 2 | S | passive | Source; body-diode forward voltage VSD ≤ 1.5 V at IS=0.75 A, VGS=0 V; continuous drain current ID=2.5 A (referenced to source). |
| 3 | D | passive | Drain; BVDSS=20 V min (ID=250 µA); RDS(ON) 55/65 mΩ typ/max at ID=3.6 A, VGS=4.5 V; continuous current ID=2.5 A, pulsed IDM=12 A. |
