CAD (KiCad official)

  • Symbol: RB400DT146
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: TO-236-3(SOT-23-3) (KiCad packages3D, STEP)
  • 3D model files: rb400dt146-etched.step / rb400dt146-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rb400dt146.step / rb400dt146.glb are the bare package body.
