BZX84C12-E3-08

Vishay Intertech · Zener Diodes · SOT-23

BZX84C12-E3-08 from Vishay Intertech, 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 Anode of the single Zener diode, shown connected to the diode in the page 1 schematic.
2 NC unconnected Shown on the page 1 schematic with no connection to the diode, so treated as not connected.
3 K passive Cathode of the single Zener diode, which conducts at the Zener voltage of 11.40 to 12.60 V (12 V nominal) at IZT1 = 5 mA for the BZX84C12.

CAD (KiCad official)

  • Symbol: BZX84C12-E3-08
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.01 mm tall, datasheet A, nominal). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: bzx84c12-e3-08-etched.step / bzx84c12-e3-08-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c12-e3-08.step / bzx84c12-e3-08.glb are the bare package body.

Provenance

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

  • Datasheet: Vishay Intertech datasheet (6 pp, sha256 d7d519b8048ee97c, retrieved 2026-11-12, tier: manufacturer)
  • 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).
