BZX84B13Q-7-F

Diodes Incorporated · Zener Diodes · SOT-23-3

BZX84B13Q-7-F from Diodes Incorporated, in a SOT-23-3. 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 at the bottom-left lead in the device schematic; it is the positive-current-return side when the diode operates in reverse breakdown.
2 NC unconnected No internal connection; the bottom-right lead has no connection in the device schematic.
3 K passive Cathode of the zener diode, shown at the single top lead in the device schematic; for BZX84B13 the zener voltage is 12.7V to 13.3V at IZT = 5.0mA.

Materials and finish

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

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

  • Symbol: BZX84B13Q-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.025 mm tall, datasheet A, nominal). 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: bzx84b13q-7-f-etched.step / bzx84b13q-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84b13q-7-f.step / bzx84b13q-7-f.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (5 pp, sha256 4d114424c6d8f3f6, 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: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
