FS3400 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 rated at ±12 V maximum, with a gate threshold voltage of 0.65 V min to 1.5 V max at ID=250uA. |
| 2 | S | passive | Source; continuous drain current is rated at 5.8 A at TA=25°C and the body diode forward drop is 1.2 V max at ISD=5.6A. |
| 3 | D | passive | Drain; drain-source voltage is rated at 30 V maximum, with pulsed drain current up to 23 A. |
