BZX84B3V6-7-F

Diodes Incorporated · Zener Diodes · SOT-23

BZX84B3V6-7-F from Diodes Incorporated, 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, the lower-left terminal in the device schematic, connected to the diode symbol.
2 NC unconnected Lower-right terminal, shown in the device schematic with no connection to the diode.
3 K passive Cathode of the zener diode, the single top terminal in the device schematic, which sets the zener voltage VZ (3.53V to 3.67V at IZT = 5mA for BZX84B3V6).
