# DZ23C22-7-F

**Diodes Incorporated** · Zener Diodes · SOT-23

DZ23C22-7-F 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 and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Anode of the first Zener diode, which shares a common cathode with the second diode; the 22V type has VZ of 20.8 to 23.3V at IZT = 5.0mA. |
| 2 | A2 | passive | Anode of the second Zener diode, which shares a common cathode with the first diode; the 22V type has VZ of 20.8 to 23.3V at IZT = 5.0mA. |
| 3 | K | passive | Common cathode of both Zener diodes, shown as the single top pin in the device schematic; the two VZ values match within 5%. |

## CAD (land: KiCad; 3D: generated from the datasheet)

- Symbol: `DZ23C22-7-F`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.025 mm tall, datasheet A, nominal). 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)
- 3D model files: `dz23c22-7-f-etched.step` / `dz23c22-7-f-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dz23c22-7-f.step` / `dz23c22-7-f.glb` are the bare package body.
