AO3405-VB

VBsemi Elec · MOSFETs · SOT-23(TO-236)

AO3405-VB from VBsemi Elec, in a SOT-23(TO-236). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: AO3405-VB
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23(TO-236), generated on the KiCad land (body 1.3 x 2.92 mm, terminals on the pads, 1.0050000000000001 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: ao3405-vb-etched.step / ao3405-vb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ao3405-vb.step / ao3405-vb.glb are the bare package body.
