BZX84-B9V1

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

BZX84-B9V1 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, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A passive Anode of the voltage regulator diode, pinned as printed in Table 2 of the datasheet.
2 n.c. unconnected Pin 2 is not connected internally and is not used in the circuit.
3 K passive Cathode of the voltage regulator diode, pinned as printed in Table 2 of the datasheet.

CAD (KiCad official)

  • Symbol: BZX84-B9V1
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23(TO-236AB), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0 mm tall, datasheet A, midpoint of min and max). Neither the vendor nor KiCad ships a 3D model for this package, so 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-b9v1-etched.step / bzx84-b9v1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84-b9v1.step / bzx84-b9v1.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 2026-11-12, 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: KiCad official libraries (CC-BY-SA 4.0).
