CAD (KiCad official)

  • Symbol: P4SOD43AX
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123F (KiCad packages3D, STEP)
  • 3D model files: p4sod43ax-etched.step / p4sod43ax-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p4sod43ax.step / p4sod43ax.glb are the bare package body.
