CAD (KiCad official)

  • Symbol: P4SMA30A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC (KiCad packages3D, STEP)
  • 3D model files: p4sma30a-etched.step / p4sma30a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p4sma30a.step / p4sma30a.glb are the bare package body.
