  • ✓Manufacturer: R+O is the brand of Zhuhai Hongjiacheng Technology Co., Ltd (R+O / 宏嘉诚科技 logo and company footer on every page of the datasheet; the maker's own site www.ichjc.com lists SMBJ6.0A, links it to LCSC C19077560, the part number on this page, and serves this datasheet from its download button)
  • •Datasheet: Rev 2.0 (PDF dated 2025-04-24) downloaded 2026-10-27 from the URL behind the www.ichjc.com download button (static.szlcsc.com/ecp/assets/hjc/new-pdf/en/SMBJ SERIES.pdf; the maker's site is hosted on that CDN). The page previously carried a JLCPCB copy marked Rev 2.1 whose text is identical apart from added uni/bi-directional symbol captions on p.1; the manufacturer's own link still serves Rev 2.0
  • ✓SMBJ6.0A row on p.2: uni-directional, marking KG, VRWM 6.0 V, VBR 6.67-7.37 V at IT 10 mA, VC 10.3 V at IPP 58.25 A, IR 800 uA
  • ✓Pins: the datasheet has no pin table; pin 1 K = cathode (band end), pin 2 A = anode, from the package outline (p.2), which marks the cathode band for uni-directional products; SMBJ6.0A is listed as uni-directional (p.2). Both passive. Descriptions rewritten from p.2
  • ✓Footprint vs the SMB/DO-214AA land dimensions (p.2): pads 2.50 x 2.30 mm at 4.30 mm centres; pad length 2.50 >= J 2.10 min, pad width 2.30 >= M 2.26 min, gap 1.80 <= K 2.74 max; pads span 0.90-3.40 mm from centre and cover the leads (G 5.08-5.59, E 0.75-1.52, lead width A 1.85-2.21). Pad 1 (x = -2.15) is the cathode
  • ✓3D body 5.30 x 3.55 x 2.15 mm against G 5.08-5.59, C 3.30-3.94, D 2.15-2.65 (height at the minimum); moulded body 4.86 mm long against B 4.25-4.85 (0.01 mm over, rounding); lead width 2.00 within A; cathode band on the top face at x -2.26 to -1.66, the pad 1 end; Z-up, seated on z = 0
  • •DigiKey and Mouser: not carried (no R+O / Hongjiacheng SMBJ6.0A listed; searched 2026-10-27)
  • ✓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

SMBJ6.0A

R+O · TVS Diodes · DO-214AA(SMB)

SMBJ6.0A from R+O, in a DO-214AA(SMB). Symbol, footprint and 3D model are the ones used on Adom board designs (KiCad official libraries). Pin functions are extracted from the manufacturer datasheet with page references.

Pinout

Pin Name Type Function
1 K passive Cathode; the terminal at the cathode band (band marked on uni-directional products only). [datasheet p.2]
2 A passive Anode; the terminal opposite the cathode band. [datasheet p.2]
