DDZX33-13

Diodes Incorporated · Zener Diodes · SOT-23

DDZX33-13 from Diodes Incorporated, in a SOT-23. 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 Zener anode, the lower-left terminal in the device schematic; the datasheet gives VZ 32.14 V min to 33.79 V max at IZT = 5 mA for the DDZX33.
2 NC unconnected The lower-right terminal in the device schematic is not connected to the diode.
3 K passive Zener cathode, the single top terminal in the device schematic; the datasheet gives a maximum reverse current of 0.05 µA at VR = 27.0 V.

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

  • Symbol: DDZX33-13
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, 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: ddzx33-13-etched.step / ddzx33-13-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddzx33-13.step / ddzx33-13.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (8 pp, sha256 f1abaaad1d27cb30, 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).
