AD-BZX84B8V2

Changjing · Zener Diodes · SOT-23

AD-BZX84B8V2 from Changjing, 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 Zener anode; the page 1 symbol shows the diode arrow pointing from pin 1 toward pin 3.
2 NC unconnected No internal connection; pin 2 is drawn as an open dot with no connection to the diode symbol.
3 K passive Zener cathode; the nominal Zener voltage is 8.2V (8.04V to 8.36V) at IZT = 5mA.

CAD (KiCad official)

  • Symbol: AD-BZX84B8V2
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ad-bzx84b8v2-etched.step / ad-bzx84b8v2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ad-bzx84b8v2.step / ad-bzx84b8v2.glb are the bare package body.

Provenance

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

  • Datasheet: Changjing datasheet (7 pp, sha256 40eb8aac4ba4d30f, retrieved 2026-10-31, 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).
