BZX84C22A from Shandong Jingdao Microelectronics, 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 single zener diode (Suffix A), connected internally to pin 3 through the diode. |
| 2 | NC | unconnected | No internal connection in the single-diode Suffix A device; pin 2 is not shown connected in the package diagram. |
| 3 | K | passive | Cathode of the single zener diode (Suffix A); zener voltage 22V nominal (20.8V to 22.44V... see review) at IZT 5mA, Ptot max 350mW. |
