CAD (KiCad official)

  • Symbol: RF081M2STR
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: rf081m2str-etched.step / rf081m2str-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rf081m2str.step / rf081m2str.glb are the bare package body.
