TPSMB24A

Public Made by Adom

by adom

Littelfuse TVS, SMB(DO-214AA). Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

CAD (KiCad official)

  • Symbol: TPSMB24A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: tpsmb24a-etched.step / tpsmb24a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpsmb24a.step / tpsmb24a.glb are the bare package body.
