SymbolFootprint3D modelPinsfor all variants
  • ✓Datasheet: Littelfuse SMF Series, Revised JC. 11/02/23, downloaded 2026-10-27 from the datasheet link on littelfuse.com's SMF6.0A product page; replaces the JLCPCB copy of the 12/06/17 edition
  • ✓SMF6.0A row (p.2): uni-directional, marking AG, VBR 6.67-7.37 V at IT 10 mA, VR 6.0 V, IR 400 uA, Ipp 19.4 A, VC 10.3 V
  • ✓Pins: the datasheet has no pin table; 'Color band denotes cathode except bipolar' (Physical Specifications, p.5) and the part marking drawing (p.6) give pin 1 K = band end, pin 2 A; both passive; descriptions rewritten from p.5
  • •Footprint vs the SOD-123FL Mounting Pad Layout (p.5): Littelfuse 1.3 x 1.4 mm pads with a 1.6 mm gap (centres +/-1.45); the KiCad footprint has 1.10 x 1.10 mm pads at +/-1.40 mm (span 0.85-1.95 mm from centre). They sit on the leads (B 3.40-3.90, E 0.35-0.90) but are narrower than the maximum lead width C 1.20 and stop 0.05 mm short of a worst-case lead's inner end; pad 1 (x = -1.40) is the cathode
  • ✓3D body 3.50 x 1.60 x 1.10 mm against B 3.40-3.90, D 1.50-2.00, H 0.90-1.10; moulded body 2.60 mm long within A 2.50-3.10; cathode band on the top face at the pad 1 end (x -1.19 to -0.79); Z-up, seated on z = 0. The model's leads are 0.65 mm wide against C 0.70-1.20 (cosmetic)
  • ✓DigiKey F5749TR-ND and Mouser 576-SMF6.0A are Littelfuse SMF6.0A (were missing on the page)
  • ✓Symbol and footprint Datasheet properties point at the manufacturer datasheet URL
  • ✓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

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
  • ✓2 of 2 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
