CAD (KiCad official)

  • Symbol: 3SMAJ5925B-TP
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: 3smaj5925b-tp-etched.step / 3smaj5925b-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 3smaj5925b-tp.step / 3smaj5925b-tp.glb are the bare package body.
