SSM3K44MFV

TOSHIBA · MOSFETs · SOT-723

SSM3K44MFV from TOSHIBA, 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 Gate input Gate terminal of the N-channel MOSFET; gate-source voltage rated ±20 V (VGSS) with Vth of 0.8 to 1.5 V at VDS = 3 V, ID = 0.1 mA.
2 Source passive Source terminal of the N-channel MOSFET, common reference for the gate and drain voltages.
3 Drain passive Drain terminal of the N-channel MOSFET; drain-source voltage rated 30 V (VDSS) and drain current 100 mA DC / 200 mA pulse.

CAD (KiCad official)

  • Symbol: SSM3K44MFV
  • 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: ssm3k44mfv-etched.step / ssm3k44mfv-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ssm3k44mfv.step / ssm3k44mfv.glb are the bare package body.
