BZT52C15 RH from Taiwan Semiconductor(Taiwan Semicon), in a SOD-123F. 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 band; connects to the positive side in zener (reverse) operation, with VZ 14.25-15.75V at IZT=5mA for BZT52C15. |
| 2 | A | passive | Anode; forward voltage VF is 1V at IF=10mA and power dissipation is limited to 500mW. |
