DDZ18ASF-7 from Diodes Incorporated, 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, the terminal marked by the cathode band; it is held positive relative to the anode in zener breakdown, where the DDZ18ASF zener voltage is 16.22 V to 17.06 V at IZT = 10 mA. |
| 2 | A | passive | Anode, the terminal opposite the cathode band; the forward voltage is 0.9 V at IF = 10 mA, and maximum power dissipation is 500 mW on FR-4. |
