BZX84-C13

Nexperia · Zener Diodes · SOT-23(TO-236AB)

BZX84-C13 from Nexperia, in a SOT-23(TO-236AB). 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 terminal of the voltage regulator diode.
2 n.c. unconnected Not connected; the datasheet states no electrical function for this pin.
3 K passive Cathode terminal of the voltage regulator diode; the cathode tab soldering point is the reference for the junction-to-solder-point thermal resistance Rth(j-sp) of 330 K/W maximum.

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

  • Symbol: BZX84-C13
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23(TO-236AB), generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.0 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: bzx84-c13-etched.step / bzx84-c13-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84-c13.step / bzx84-c13.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (14 pp, sha256 e6278027e055c1b0, retrieved 2026-11-13, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-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).
