Diodes Incorporated · Zener Diodes · SOT-323
BZX84C22W-7-F from Diodes Incorporated, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Anode of the Zener diode, shown on a bottom pin of the device schematic, with a forward voltage of 0.9 V at IF = 10 mA. |
| 2 | NC | unconnected | No internal connection; the device schematic shows this bottom pin without a connection to the diode. |
| 3 | K | passive | Cathode of the Zener diode, shown on the single top pin of the device schematic, with a nominal Zener voltage of 22 V (20.8 V to 23.3 V) at IZT = 5 mA for the BZX84C22W. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
BZX84C22W-7-F - Footprint:
Package_TO_SOT_SMD:SOT-323_SC-70 - 3D model: SOT-323, generated on the KiCad land (body 1.25 x 2.1 mm, terminals on the pads, 0.95 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
