27 Oct 2026Claude, at Caleb Taylor's requestValidated against Littelfuse's SP05 Series datasheet (Revised GD. 10/21/22); 3D model rebuilt to the package tablefiles match
SymbolFootprint3D modelPinsfor all variants
  • ✓Datasheet: Littelfuse SP05 Series (SP050xBA lead-free/green), Revised GD. 10/21/22, downloaded 2026-10-27 from the datasheet link on littelfuse.com's SP0504BAHTG product page; replaces a 2009 copy whose PDF metadata names alldatasheet.com
  • ✓Pins against the SP0504BAHTG pinout drawing (p.1): pins 1, 3, 4, 5 are diode cathodes (channels), pin 2 is the common anode; the datasheet prints no pin names, so K/A are kept; all passive; descriptions rewritten (p.1, ground from note 1 p.2)
  • •Footprint vs the SOT23-5 Recommended Pad Layout (p.5): Littelfuse pads 0.69 x 0.99 mm at 2.59 mm row spacing and 0.95 mm pitch (pad span 0.80-1.79 mm from centre); the KiCad footprint has 1.325 x 0.60 mm pads at 2.275 mm row spacing (span 0.475-1.80) and the same 0.95 mm pitch. The pads cover the Littelfuse pad area lengthwise and the leads (b 0.25-0.50, E 2.6-3.0, L1 0.60 REF); pin 1 top-left, 2 middle-left, 3 bottom-left, 4 bottom-right, 5 top-right: the datasheet top view rotated 90 degrees, not mirrored
  • ✓DigiKey F3157TR-ND and Mouser 576-SP0504BAHTG confirmed as Littelfuse SP0504BAHTG (searched 2026-10-27)
  • ✓3D source: tier 1 none (Littelfuse's SP0504BAHTG product page offers 3D only as "Partner ECAD Models" (SamacSys, catalog SP0504BAHTG&epm=0): a third-party library behind its own account and terms, not a manufacturer original with redistribution terms (2026-10-27).) Tier 2 rejected (KiCad Package_TO_SOT_SMD.3dshapes/SOT-23-5.step: 2.80 x 2.90 x 1.55 mm, A max 1.45: out of tolerance. TSOT-23-5.step (0.95 mm) models the thin TSOT package, not this part's SOT23-5 (MO-178): not used.) Tier 3: model rebuilt with the KiCad 3D model generator (gitlab.com/kicad/libraries/kicad-packages3D-generator, commit e272fcc8) from Littelfuse SP05 Series (SP050xBA) datasheet Revised: GD. 10/21/22, Package Dimensions SOT23-5, p.5; parameters in provenance/3d-generator-params.yaml; Adom-authored, CC-BY-SA-4.0
  • ✓3D body vs drawing: body 2.90 x 1.60 mm at the parting line: D 2.75-3.05, E1 1.45-1.75: pass; lead span 2.80: E 2.6-3.0: pass; overall height 1.225 mm (etched 1.23): A max 1.45: pass; standoff 0.075: A1 0-0.15: pass; leads 0.375 wide, 0.15 thick, 0.60 from body to tip: b 0.25-0.5, c 0.08-0.22, L1 0.60 REF: pass; leads: three at x -1.40..-1.05 (y -0.95, 0, +0.95), two at x +1.05..+1.40 (y +/-0.95): on footprint pads 1-3 (x -1.1375) and 4-5 (x +1.1375): pass; no pin-1 dot on the part (marking 504B only): none modelled
  • ✓3D pose: sp0504bahtg.step and sp0504bahtg-etched.step are Z-up, seated on z = 0, centred on the footprint origin (offset 0.0 mm), footprint (model) binding identity (step_pose.py); the source was built in the footprint frame, so the transform is identity; the etched file adds the adom-chip-laser MPN inlay on the top face; GLBs from step2glb convert; footprint (model) path now ${KIPRJMOD}/sp0504bahtg.step with only that line changed (pads untouched); provenance/3d-model.json records source, terms, hashes, transform and checks
  • •Model height: Littelfuse gives A as a maximum only (1.45 mm); the model uses A1 0.075 (mid of 0-0.15) and a 1.15 mm body, A = 1.225 mm
  • ✓Symbol Datasheet / MPN / Manufacturer / DigiKey / Mouser / LCSC properties agree with page.json; footprint Datasheet property points at the manufacturer datasheet URL
  • ✓component-page-verify: all checks pass

  • •The datasheet pinout is a drawing with no pin names; the K/A names come from the KiCad Power_Protection:SP0504BAHT symbol and agree with the drawing (pin 2 is the common anode).

SymbolFootprint3D modelPinsfor all variants
  • ✓Footprint extracted pad-for-pad from the source board and normalized to the footprint frame (back-side parts un-mirrored)
  • ✓3D model seated z=0 at footprint origin (placement inverse; method centroid-matched to KiCad library models on 59 cases)
  • ✓adom-lbr generate + lint passed
  • ✓5 of 5 pins described from the datasheet (adom-ds2sf, page-cited)
  • •Not yet checked by a person: land pattern vs datasheet, pin-1/orientation, 3D body vs drawing
