BZB84-B18

Nexperia · Zener Diodes · SOT-23

BZB84-B18 from Nexperia, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K1 passive Cathode of Zener diode 1. Reverse breakdown (Zener) voltage V_Z = 17.60 V to 18.40 V at I_Z = 5 mA; forward voltage V_F ≤ 0.9 V at I_F = 10 mA. Non-repetitive peak reverse current I_ZSM ≤ 1.5 A (t_p = 100 µs).
2 K2 passive Cathode of Zener diode 2. Reverse breakdown (Zener) voltage V_Z = 17.60 V to 18.40 V at I_Z = 5 mA; forward voltage V_F ≤ 0.9 V at I_F = 10 mA. Non-repetitive peak reverse current I_ZSM ≤ 1.5 A (t_p = 100 µs).
3 A passive Common anode shared by both Zener diodes (dual common-anode configuration). Total power dissipation for the device is limited to 300 mW at T_amb ≤ 25 °C.

  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bzb84-b18-etched.step / bzb84-b18-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzb84-b18.step / bzb84-b18.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (14 pp, sha256 d909f500a84da6be, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
