LGE · Zener Diodes · SOT-23
BZX84C51 from LGE, 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 | ANODE | passive | Anode terminal of the zener diode, labelled ANODE on the datasheet pin drawing; the device is rated 350 mW power dissipation at Ta=25°C. |
| 2 | NC | unconnected | The extracted text gives no function for pin 2 beyond a stray '2' after the ANODE label, so its role could not be confirmed from the text and should be checked against the package drawing. |
| 3 | CATHODE | passive | Cathode terminal of the zener diode, labelled cathode on the datasheet pin drawing; operating and storage temperature range is -65 to +150 °C. |
