SMAJ3.3LIR

Public Made by Adom

by adom

Leiditech TVS, DO-214AC(SMA). 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: SMAJ3.3LIR
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: smaj3-3lir-etched.step / smaj3-3lir-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj3-3lir.step / smaj3-3lir.glb are the bare package body.

Provenance

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

  • Datasheet: Leiditech datasheet (3 pp, sha256 0ba9aff5d6bc9744, retrieved 2026-10-22, 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).
