FS3415K

FUXINSEMI · MOSFETs · SOT-23

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.
