DDZ9709-7 from Diodes Incorporated, in a SOD-123. 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, identified by the cathode band on the package; the DDZ9709 zener voltage is 24V nominal (22.8V to 25.2V) at IZT = 50µA. |
| 2 | A | passive | Anode, the terminal opposite the cathode band; forward voltage is 0.9V at IF = 10mA and power dissipation is 500mW. |
