FS2302 from FOSAN, in a SOT-23-3L. 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 limited to ±10 V absolute maximum, with threshold of 0.5 to 1.1 V at ID=250uA. |
| 2 | S | passive | Source; continuous drain current is 4.3 A at TA=25°C and the body diode forward drop is 1.2 V max at ISD=4A. |
| 3 | D | passive | Drain; drain-source breakdown voltage is 20 V min, with 4.3 A continuous and 16 A pulsed drain current. |
