CAD (KiCad official)

  • Symbol: TS1231LKX
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: ts1231lkx-etched.step / ts1231lkx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ts1231lkx.step / ts1231lkx.glb are the bare package body.
