3SMB5929B

LGE · Zener Diodes · SMB

3SMB5929B from LGE, 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 end marked with the color band; positive terminal in reverse-breakdown operation, VZ 15 V nominal at IZT = 25.0 mA (±5% tolerance).
2 A passive Anode, the end without the color band; maximum forward voltage 1.5 V at IF = 200 mA.

CAD (KiCad official)

  • Symbol: 3SMB5929B
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: 3smb5929b-etched.step / 3smb5929b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 3smb5929b.step / 3smb5929b.glb are the bare package body.

Provenance

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

  • Datasheet: LGE datasheet (5 pp, sha256 3b15c982b0998b75, retrieved 2026-10-13, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-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).
