LBZX84C20LT1G 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 of the zener diode, per the datasheet pinout (1-Anode, 2-No Connection, 3-Cathode); the LBZX84C20LT1G has a nominal VZ of 20 V (18.8 V min to 21.2 V max at IZT1 = 5 mA). |
| 2 | NC | unconnected | No internal connection; the datasheet pinout lists this pin as No Connection. |
| 3 | Cathode | passive | Cathode of the zener diode; device total dissipation is 225 mW on an FR-5 board or 300 mW on an alumina substrate at TA = 25°C. |
