DDZX8V2C-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 8.2V precision Zener (VZ 8.03V to 8.45V at IZT = 20mA); the schematic shows it on the bottom-left terminal. |
| 2 | NC | unconnected | No internal connection; the device schematic shows no element on the bottom-right terminal. |
| 3 | K | passive | Cathode of the Zener, on the single top terminal; it is positive in normal reverse-breakdown operation (300mW maximum power dissipation on FR-4). |
