BZX84C5V1Q-7-F

Diodes Incorporated · Zener Diodes · SOT-23

BZX84C5V1Q-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 (bottom-left terminal in the device schematic), connected to the diode's anode side.
2 NC unconnected No internal connection; the bottom-right terminal in the device schematic is not connected to the diode.
3 K passive Cathode of the Zener diode (top terminal in the device schematic); the 5.1V Zener (BZX84C5V1) voltage is 4.8V min to 5.4V max at IZT = 5.0mA.
