TPSMB100A

Public Made by Adom

by adom

Littelfuse TVS, 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: TPSMB100A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA (KiCad packages3D, STEP)
  • 3D model files: tpsmb100a-etched.step / tpsmb100a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpsmb100a.step / tpsmb100a.glb are the bare package body.

Provenance

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

  • Datasheet: Littelfuse datasheet (6 pp, sha256 0ac950ffb3161f3d, retrieved 2026-10-31, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary cathode-band convention (convention), consensus off (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
