FS3415K from FUXINSEMI, 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 of the P-channel MOSFET, ESD protected up to 2.0KV (HBM), with the RDS(on) of 48mΩ max specified at VGS = -4.5V. |
| 2 | S | passive | Source of the P-channel MOSFET, connected to the body diode anode and the gate ESD protection element in the circuit diagram. |
| 3 | D | passive | Drain of the P-channel MOSFET, rated for VDS of -20V and continuous drain current of -4.2A. |
