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.
