FS3402 A2LA 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 is limited to ±12 V, with threshold VGS(th) of 0.65 V min, 0.9 V typ and 1.5 V max at ID=250uA. |
| 2 | S | passive | Source; continuous drain current is rated 5.8 A at TA=25°C, and the body diode forward drop is 1.2 V max at ISD=5.6 A. |
| 3 | D | passive | Drain; drain-source voltage is rated 30 V, continuous drain current 5.8 A and pulsed drain current 23 A. |
