PDZ5.1B from Nexperia, in a SOD-323. 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, indicated by the marking bar on the package; the Zener regulates reverse breakdown voltage between cathode and anode. |
| 2 | A | passive | Anode of the Zener diode, the terminal opposite the cathode marking bar. |
