LBZX84C4V3LT1G from LRC, 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 regulator diode; the datasheet's SOT-23 figure and electrical table both assign pin 1 as Anode. |
| 2 | NC | unconnected | No connection; the datasheet's electrical table lists pin 2 as No Connection, so it should be left unconnected. |
| 3 | Cathode | passive | Cathode terminal of the zener regulator diode; the datasheet's SOT-23 figure and electrical table both assign pin 3 as Cathode. |
