FS1012ET

FUXINSEMI · MOSFETs · SOT-523

FS1012ET from FUXINSEMI, in a SOT-523. 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 limited to ±8 V absolute maximum, with gate threshold of 0.45 V min to 1.2 V max at VDS=VGS, ID=250µA, and ESD protection shown in the circuit diagram.
2 S passive Source terminal of the N-channel MOSFET, with the body diode between source and drain (forward voltage 1.2 V max at IS=0.3A).
3 D passive Drain terminal; drain-source voltage rated 20 V, continuous drain current 0.7 A and pulsed drain current 2.8 A.

CAD (KiCad official)

  • Symbol: FS1012ET
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: fs1012et-etched.step / fs1012et-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fs1012et.step / fs1012et.glb are the bare package body.
