# DZ23C13-7-F

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

DZ23C13-7-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, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Anode of the first Zener diode (bottom-left terminal in the top-view schematic); VZ is 12.4 to 14.1 V at IZT = 5.0mA for the DZ23C13. |
| 2 | A2 | passive | Anode of the second Zener diode (bottom-right terminal in the top-view schematic); VZ is matched to the first diode within 5%. |
| 3 | K | passive | Common cathode of both Zener diodes (top terminal in the top-view schematic), with 300mW total power dissipation. |

## CAD (KiCad official)

- Symbol: `DZ23C13-7-F`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.025 mm tall, datasheet A, nominal). Neither the vendor nor KiCad ships a 3D model for this package, so 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: `dz23c13-7-f-etched.step` / `dz23c13-7-f-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dz23c13-7-f.step` / `dz23c13-7-f.glb` are the bare package body.
