BZT52C12-WH-SOD-123 from SY(顺烨), in a SOD-123. 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, marked by the cathode bar on the body; it goes positive in zener reverse breakdown, with total power dissipation limited to 500 mW. |
| 2 | A | passive | Anode, the terminal opposite the cathode bar; forward voltage is 0.9 V at IF=10 mA. |
