SMAJ190A

Public Made by Adom

by adom

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

SMAJ190A

TKS · TVS · DO-214AC

SMAJ190A from TKS, in a DO-214AC. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode: the banded/marked end per the datasheet; pad 1 of the KiCad diode footprint.
2 A passive Anode.

CAD (KiCad official)

  • Symbol: SMAJ190A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC (KiCad packages3D, STEP)
  • 3D model files: smaj190a-etched.step / smaj190a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj190a.step / smaj190a.glb are the bare package body.

Provenance

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

  • Datasheet: TKS datasheet (16 pp, sha256 8a31c496d2339017, retrieved 2026-10-30, 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).
