BZX84C3V3-TP

MCC(Micro Commercial Components) · Zener Diodes · SOT-23

BZX84C3V3-TP from MCC(Micro Commercial Components), 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 (3.3V nominal, 3.10V to 3.50V at IZT=5mA); read from the internal structure drawing, where the left bottom pin connects to the diode's non-bar side.
2 NC unconnected No internal connection; the internal structure drawing shows this pin with no connection to the diode.
3 K passive Cathode of the zener diode, the top pin in the internal structure drawing, connected to the diode bar side; power dissipation is 350mW.

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

  • Symbol: BZX84C3V3-TP
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.92 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: bzx84c3v3-tp-etched.step / bzx84c3v3-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c3v3-tp.step / bzx84c3v3-tp.glb are the bare package body.

Provenance

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

  • Datasheet: MCC(Micro Commercial Components) datasheet (5 pp, sha256 1efe3e00c68b7755, retrieved 2026-11-13, 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).
