NSI45030AT1G

onsemi · LED Drivers · SOD-123

NSI45030AT1G from onsemi, in a SOD-123. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode terminal of the constant current regulator. Current flows into the anode and out of the cathode, regulated to Ireg(SS) = 30 mA typ at Vak = 7.5 V.
2 A passive Anode terminal of the constant current regulator. Max anode-cathode voltage Vak = 45 V; regulated current 30 mA typ (27/33 min/max) at Vak = 7.5 V with only ~1.8 V voltage overhead.

CAD (KiCad official)

  • Symbol: NSI45030AT1G
  • Footprint: Diode_SMD:D_SOD-123
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: nsi45030at1g-etched.step / nsi45030at1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); nsi45030at1g.step / nsi45030at1g.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
nsi45030at1g.step 52 KB You want the bare part, or you mark your own boards.
nsi45030at1g-etched.step 2.1 MB You want the part with NSI45030AT1G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 532 faces against 59 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: onsemi datasheet (8 pp, sha256 588a3e4ece87e39d, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
