LBZX84C3V3LT1G 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 BZX84C3V3LT1G zener diode; the datasheet pinout lists pin 1 as Anode for the SOT-23 package. |
| 2 | NC | unconnected | No internal connection; the datasheet pinout states pin 2 is No Connection. |
| 3 | Cathode | passive | Cathode terminal of the zener diode, which regulates at a nominal VZ of 3.3 V at IZT = 5 mA per the electrical table for the LBZX84C3V3LT1G. |
