CAD (KiCad official)

  • Symbol: BTLC05VD523B
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: btlc05vd523b-etched.step / btlc05vd523b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); btlc05vd523b.step / btlc05vd523b.glb are the bare package body.
