CAD (KiCad official)

  • Symbol: BZX84C18Q
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23(TO-236) (KiCad packages3D, STEP)
  • 3D model files: bzx84c18q-etched.step / bzx84c18q-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c18q.step / bzx84c18q.glb are the bare package body.
