CAD (KiCad official)

  • Symbol: MURA120T3G-JSM
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: mura120t3g-jsm-etched.step / mura120t3g-jsm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mura120t3g-jsm.step / mura120t3g-jsm.glb are the bare package body.
