# BZX84C22V

**JUXING** · Zener Diodes · SOT-23

BZX84C22V from JUXING, 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 | Zener diode anode, shown on the pin 1 side of the diode symbol; the 22V nominal Zener voltage (20.8V to 23.3V at IZT=5mA) is measured from cathode pin 3 to this pin. |
| 2 | NC | unconnected | Pin 2 is drawn with no connection to the diode in the internal schematic, so it is not connected. |
| 3 | K | passive | Zener diode cathode, shown on the pin 3 side of the diode symbol; the device dissipates up to 300mW. |
