CAD (KiCad official)

  • Symbol: SMAJ7.5CA-13-F
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: smaj7-5ca-13-f-etched.step / smaj7-5ca-13-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj7-5ca-13-f.step / smaj7-5ca-13-f.glb are the bare package body.

Provenance
