# BZT52C5V1-13-F

**Diodes Incorporated** · Zener Diodes · SOD-123

BZT52C5V1-13-F 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, the terminal marked by the cathode band on the package; it goes positive relative to the anode in Zener breakdown (VZ 4.8 V min to 5.4 V max at IZT = 5 mA for the 5.1 V type). |
| 2 | A | passive | Anode, the terminal opposite the cathode band; forward voltage is 0.9 V at IF = 10 mA. |

## CAD (KiCad official)

- Symbol: `BZT52C5V1-13-F`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `bzt52c5v1-13-f-etched.step` / `bzt52c5v1-13-f-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bzt52c5v1-13-f.step` / `bzt52c5v1-13-f.glb` are the bare package body.
