# DZL4761

**LGE** · Zener Diodes · SOD-123FL

DZL4761 from LGE, in a SOD-123FL. 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, marked by the laser band on the package; connected to the positive side in reverse-biased zener operation (DZL4761 VZ 75 V nominal, 71.25 to 78.75 V at IZT 3.3 mA). |
| 2 | A | passive | Anode terminal of the glass passivated zener diode (power dissipation 1.0 W, junction temperature 150 °C max). |

## CAD (KiCad official)

- Symbol: `DZL4761`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `dzl4761-etched.step` / `dzl4761-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dzl4761.step` / `dzl4761.glb` are the bare package body.
