CAD (KiCad official)

  • Symbol: RFN2LAM4STFTR
  • Footprint: Diode_SMD:D_SOD-128
  • 3D model: SOD-128 (KiCad packages3D, STEP)
  • 3D model files: rfn2lam4stftr-etched.step / rfn2lam4stftr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rfn2lam4stftr.step / rfn2lam4stftr.glb are the bare package body.
