BZX84C9V1Q-13-F

Diodes Incorporated · Zener Diodes · SOT-23

BZX84C9V1Q-13-F 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 Anode of the Zener diode, the lower-left terminal in the device schematic; connect to the more negative side of the circuit (9.1V nominal Zener at IZT = 5.0mA for the C9V1 type).
2 NC unconnected No internal connection; the lower-right terminal is shown as a bare lead in the device schematic.
3 K passive Cathode of the Zener diode, the top terminal in the device schematic; it is the positive side for reverse Zener operation (9.1V nominal, 8.5V to 9.6V at IZT = 5.0mA for the C9V1 type).

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

  • Symbol: BZX84C9V1Q-13-F
  • 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: bzx84c9v1q-13-f-etched.step / bzx84c9v1q-13-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c9v1q-13-f.step / bzx84c9v1q-13-f.glb are the bare package body.
