BZT52C13-WI 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; for BZT52C13 the zener voltage is 12.4V min to 14.1V max at IZT=5mA. |
| 2 | A | passive | Anode, the terminal opposite the cathode bar; total power dissipation is max 500mW and forward voltage is 0.9V at IF=10mA. |
