BZX84C4V3Q-13-F

Diodes Incorporated · Zener Diodes · SOT-23

BZX84C4V3Q-13-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.
2 NC unconnected No internal connection; the lower-right terminal in the device schematic has no connection to the die.
3 K passive Cathode of the Zener diode, the single top terminal in the device schematic (BZX84C4V3 VZ 4.0V to 4.6V at IZT = 5.0mA).
