BZX84C12W-7-F

Diodes Incorporated · Zener Diodes · SOT-323

BZX84C12W-7-F from Diodes Incorporated, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function
1 A passive Anode of the 12V Zener diode (Zener voltage 11.4V min to 12.7V max at IZT = 5mA), shown at the bottom-left of the device schematic.
2 NC unconnected No internal connection; the bottom-right lead is not connected to the diode in the device schematic.
3 K passive Cathode of the Zener diode, the single lead at the top of the device schematic; it goes positive relative to the anode in the Zener breakdown direction.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: BZX84C12W-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323, generated on the KiCad land (body 1.25 x 2.1 mm, terminals on the pads, 0.95 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; 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: bzx84c12w-7-f-etched.step / bzx84c12w-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c12w-7-f.step / bzx84c12w-7-f.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (4 pp, sha256 d9219bc3aedc6fa2, retrieved 2026-11-13, 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: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
