BZT52C16Q from Yangzhou Yangjie Elec Tech, 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 end marked with the cathode line; it goes positive relative to the anode in zener breakdown (VZ 15.3V min, 16V typ, 17.1V max at IZT=5mA for the BZT52C16Q). |
| 2 | A | passive | Anode, the end opposite the cathode line; maximum forward voltage is 0.9V at IF=10mA and power dissipation is 500mW. |
