CAD (KiCad official)

  • Symbol: 3.0SMC24A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: DO-214AB(SMCJ) (KiCad packages3D, STEP)
  • 3D model files: 3-0smc24a-etched.step / 3-0smc24a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 3-0smc24a.step / 3-0smc24a.glb are the bare package body.
