KM3139K

KUU · MOSFETs · SOT-723

KM3139K from KUU, in a SOT-723. 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; controls the channel with VGS limited to ±12 V, threshold VGS(th) -0.35 to -0.8 V at ID = -250 µA, and ESD protected up to 2 kV (HBM).
2 S passive Source of the P-channel MOSFET; continuous drain current ID is -0.66 A (pulsed -1.2 A).
3 D passive Drain of the P-channel MOSFET; drain-source voltage VDS is rated -20 V and the body diode is connected between drain and source.

CAD (KiCad official)

  • Symbol: KM3139K
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 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: km3139k-etched.step / km3139k-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); km3139k.step / km3139k.glb are the bare package body.
