DDZX15-7 from Diodes Incorporated, in a SOT-23. 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 | A | passive | Anode of the zener diode, the lower-left lead in the top-view device schematic. |
| 2 | NC | unconnected | No internal connection; the lower-right lead is not connected to the diode in the device schematic. |
| 3 | K | passive | Cathode of the zener diode, the single top lead in the device schematic; the DDZX15 has VZ of 14.80 to 15.57 V at IZT = 10 mA. |
