# BZT52-C75J

**Nexperia** · Zener Diodes · SOD-123

BZT52-C75J from Nexperia, in a SOD-123. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode of the Zener diode. Marked with a bar on the package body. Reverse breakdown (Zener) voltage Vz = 70.0 V to 79.0 V at Iz = 2 mA for the -C75 variant; non-repetitive peak reverse current IZSM = 0.20 A max. |
| 2 | A | passive | Anode of the Zener diode. Forward current IF up to 250 mA max; forward voltage VF <= 0.9 V at IF = 10 mA. |

## CAD (KiCad official)

- Symbol: `BZT52-C75J`
- Footprint: `Diode_SMD:D_SOD-123`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `bzt52-c75j-etched.step` / `bzt52-c75j-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bzt52-c75j.step` / `bzt52-c75j.glb` are the bare package body.
