BZX84C22W-7-F

Diodes Incorporated · Zener Diodes · SOT-323

BZX84C22W-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 Zener diode, shown on a bottom pin of the device schematic, with a forward voltage of 0.9 V at IF = 10 mA.
2 NC unconnected No internal connection; the device schematic shows this bottom pin without a connection to the diode.
3 K passive Cathode of the Zener diode, shown on the single top pin of the device schematic, with a nominal Zener voltage of 22 V (20.8 V to 23.3 V) at IZT = 5 mA for the BZX84C22W.

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: BZX84C22W-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: bzx84c22w-7-f-etched.step / bzx84c22w-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c22w-7-f.step / bzx84c22w-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).
