BZT52C11V-WG from ShunYe, 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, the terminal marked with the cathode bar on the body; it goes positive in reverse (zener) operation, with a power dissipation limit of 500mW. |
| 2 | A | passive | Anode, the terminal opposite the cathode bar; forward voltage is 0.9V at IF=10mA. |
