CAD (KiCad official)

  • Symbol: PZT2222A
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: pzt2222a-etched.step / pzt2222a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pzt2222a.step / pzt2222a.glb are the bare package body.
