BZX84C9V1A

Shandong Jingdao Microelectronics · Zener Diodes · SOT-23

BZX84C9V1A from Shandong Jingdao Microelectronics, 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 Anode of the single zener diode (Suffix A), per the package diagram where the diode symbol runs from pin 1 to pin 3.
2 NC unconnected Not connected internally in the single-diode Suffix A device; the diagram shows no internal connection to pin 2.
3 K passive Cathode of the single zener diode (Suffix A), connected to the diode's cathode side in the package diagram.

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

  • Symbol: BZX84C9V1A
  • 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, 1.0 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: bzx84c9v1a-etched.step / bzx84c9v1a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c9v1a.step / bzx84c9v1a.glb are the bare package body.

Provenance

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

  • Datasheet: Shandong Jingdao Microelectronics datasheet (4 pp, sha256 15f9741a37e514a5, retrieved 2026-11-12, tier: lcsc)
  • 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).
