CAD (KiCad official)

  • Symbol: STTH3R04U
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA (KiCad packages3D, STEP)
  • 3D model files: stth3r04u-etched.step / stth3r04u-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stth3r04u.step / stth3r04u.glb are the bare package body.
