S-LBZX84C33LT1G 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 diode, identified as pin 1 in the SOT-23 pinout for the BZX84Cxx LT1 series. |
| 2 | NC | unconnected | No internal connection; the datasheet lists this pin as no connection. |
| 3 | Cathode | passive | Cathode terminal of the zener diode, identified as pin 3 in the SOT-23 pinout for the BZX84Cxx LT1 series. |
