AD-BZX84B15

Changjing · Zener Diodes · SOT-23

AD-BZX84B15 from Changjing, 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 A passive Anode of the zener diode (pin 1 in the symbol on page 1); the AD-BZX84B15 has a nominal Vz of 15V (14.70-15.30V) at IZT = 5mA.
2 NC unconnected Pin 2 is drawn in the page 1 symbol with no connection to the diode, so it is not connected internally.
3 K passive Cathode of the zener diode (pin 3 in the symbol on page 1); it is the reverse breakdown terminal, with a 300mW power dissipation rating.
