BZB84-C15

Nexperia · Zener Diodes · SOT-23

BZB84-C15 from Nexperia, in a SOT-23. 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	cathode (diode 1)	passive	Cathode of Zener diode 1 in the dual common-anode configuration; the datasheet gives no pin-specific electrical limit for this pin.
2	cathode (diode 2)	passive	Cathode of Zener diode 2 in the dual common-anode configuration; the datasheet gives no pin-specific electrical limit for this pin.
3	common anode	passive	Common anode shared by both Zener diodes; the datasheet gives no pin-specific electrical limit for this pin.

CAD (KiCad official)

Symbol: BZB84-C15
Footprint: Package_TO_SOT_SMD:SOT-23
3D model: SOT-23 (KiCad packages3D, STEP)
3D model files: bzb84-c15-etched.step / bzb84-c15-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzb84-c15.step / bzb84-c15.glb are the bare package body.
