CAD (KiCad official)

  • Symbol: PDTC144ET
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: pdtc144et-etched.step / pdtc144et-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pdtc144et.step / pdtc144et.glb are the bare package body.
