  • Symbol: SMC30J58CA
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: smc30j58ca-etched.step / smc30j58ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smc30j58ca.step / smc30j58ca.glb are the bare package body.
