CMSN1012H3-HF

Comchip · MOSFETs · SOT-523

CMSN1012H3-HF from Comchip, 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 limit is ±8 V with VGS(th) 0.5 to 1.2 V at ID=250 µA.
2 S passive Source; continuous drain current is 560 mA at TA=25 °C and VGS=4.5 V.
3 D passive Drain; drain-source voltage is rated 20 V, with pulsed drain current of 2.5 A.

CAD (KiCad official)

  • Symbol: CMSN1012H3-HF
  • 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: cmsn1012h3-hf-etched.step / cmsn1012h3-hf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cmsn1012h3-hf.step / cmsn1012h3-hf.glb are the bare package body.
