S-SMBJ58A

LRC · TVS · SMB

S-SMBJ58A from LRC, in a SMB. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode, the terminal marked by the color band on the SMB body (polarity per the Mechanical Data section).
2 A passive Anode, the unmarked terminal opposite the color band on the SMB body.

CAD (KiCad official)

  • Symbol: S-SMBJ58A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: s-smbj58a-etched.step / s-smbj58a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s-smbj58a.step / s-smbj58a.glb are the bare package body.

Provenance

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

  • Datasheet: LRC datasheet (4 pp, sha256 706efabab80fb6fe, retrieved 2026-10-22, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text), consensus claude-sonnet-5-5 (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).
