CAD (KiCad official)

  • Symbol: CH423NTB
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92S (KiCad packages3D, STEP)
  • 3D model files: ch423ntb-etched.step / ch423ntb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ch423ntb.step / ch423ntb.glb are the bare package body.
