CAD (KiCad official)

  • Symbol: STTH2R02AY
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: stth2r02ay-etched.step / stth2r02ay-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stth2r02ay.step / stth2r02ay.glb are the bare package body.
