LBZX84C75LT1G 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 | Zener diode anode per the datasheet pinout (1-Anode); the forward voltage is 0.90 V max at IF = 10 mA. |
| 2 | NC | unconnected | No connection; the datasheet pinout lists pin 2 as No Connection. |
| 3 | Cathode | passive | Zener diode cathode per the datasheet pinout (3-Cathode); for LBZX84C75LT1G the zener voltage VZ is 75 V nominal (70 V min, 79 V max) at IZT1 = 5 mA. |
