FS3401M

FOSAN · MOSFETs · SOT-23

FS3401M from FOSAN, 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 enhancement MOSFET, with VGS rated at ±12 V maximum and gate threshold VGS(th) of -0.6 V min, -0.9 V typ and -1.4 V max at ID = -250 uA.

CAD (KiCad official)

  • Symbol: FS3401M
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: fs3401m-etched.step / fs3401m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fs3401m.step / fs3401m.glb are the bare package body.
