CAD (KiCad official)

  • Symbol: WST6005
  • 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: wst6005-etched.step / wst6005-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); wst6005.step / wst6005.glb are the bare package body.
