CAD (KiCad official)

  • Symbol: PTZ24B
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: ptz24b-etched.step / ptz24b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ptz24b.step / ptz24b.glb are the bare package body.
