CAD (KiCad official)

  • Symbol: MJ15015G
  • Footprint: Package_TO_SOT_THT:TO-3
  • 3D model: TO-3 (KiCad packages3D, STEP)
  • 3D model files: mj15015g-etched.step / mj15015g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mj15015g.step / mj15015g.glb are the bare package body.
