**Yangzhou Yangjie Elec Tech** · Zener Diodes · SOD-523(SC-79)

BZX584C12V from Yangzhou Yangjie Elec Tech, in a SOD-523(SC-79). 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 | K | passive | Cathode, the end marked by the cathode line on the package; it goes positive of the anode in zener (reverse) operation, with Vz 11.4V min, 12V typ and 12.7V max at IZT=5mA for the BZX584C12V. |
| 2 | A | passive | Anode; the forward voltage is 1.0V at 10mA, and power dissipation is limited to 200mW at Ta=25°C. |
