BZX84C12 from hongjiacheng, 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, shown in the function diagram as the diode's anode side; the zener voltage VZ for BZX84C12 is 12V nominal (11.4V to 12.7V) at IZT=5mA. |
| 2 | NC | unconnected | Pin 2 is shown in the function diagram with no internal connection to the diode. |
| 3 | K | passive | Cathode of the zener diode, marked by the cathode line on the package; power dissipation is limited to 300mW. |
