BZX84B11

LGE · Zener Diodes · SOT-23

BZX84B11 from LGE, in a SOT-23. 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 A passive Pin 1 is the cathode end of the Zener diode (symbol shows 1 connected through the diode to 3); the datasheet gives VZ 10.8-11.2 V (11 V nominal) at IZT1 = 5 mA for BZX84B11.
2 NC unconnected Pin 2 is shown as an unconnected open terminal in the package schematic, with no function stated.
3 K passive Pin 3 is the second diode terminal, joined to pin 1 through the Zener in the schematic; the rating is 300 mW power dissipation and Tj 150 °C.

CAD (KiCad official)

  • Symbol: BZX84B11
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bzx84b11-etched.step / bzx84b11-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84b11.step / bzx84b11.glb are the bare package body.

Provenance

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

  • Datasheet: LGE datasheet (4 pp, sha256 ada4fe229d103623, retrieved 2026-11-04, 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).
