SSM3K44FS

TOSHIBA · MOSFETs · SOT-416

SSM3K44FS from TOSHIBA, in a SOT-416. 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; VGSS rating is ±20 V and VGS(on) must exceed Vth (0.8 to 1.5 V at VDS = 3 V, ID = 0.1 mA).
2 SOURCE passive Source terminal of the N-channel MOSFET, shown on the equivalent circuit tied to the body diode anode.
3 DRAIN passive Drain terminal of the N-channel MOSFET; VDSS is 30 V, ID is 100 mA DC and 200 mA pulsed.

CAD (KiCad official)

  • Symbol: SSM3K44FS
  • Footprint: Package_TO_SOT_SMD:SOT-416
  • 3D model: SOT-416, 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: ssm3k44fs-etched.step / ssm3k44fs-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ssm3k44fs.step / ssm3k44fs.glb are the bare package body.
