Diodes Incorporated · Zener Diodes · SOD-323F
DDZ33CSF-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, which goes positive relative to the anode in zener breakdown (VZ 30.90V min to 32.50V max at IZT = 5mA for DDZ33CSF). |
| 2 | A | passive | Anode, the terminal opposite the cathode band, with forward voltage VF of 0.9V at IF = 10mA. |
