CAD (KiCad official)

  • Symbol: TPSMB30CA
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA (KiCad packages3D, STEP)
  • 3D model files: tpsmb30ca-etched.step / tpsmb30ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpsmb30ca.step / tpsmb30ca.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
