PZU15B from Nexperia, in a SOD-323F. 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 of the Zener diode, marked by the marking bar; soldering point is the cathode tab, and a 1 cm² cathode mounting pad gives Ptot of 550 mW. |
| 2 | A | passive | Anode of the Zener diode. |
