**LRC** · Zener Diodes · SOT-23

LBZX84C8V2LT1G 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 pinout lists pin 1 as Anode for the BZX84C series, and the forward voltage is VF = 0.90 V max at IF = 10 mA. |
| 2 | No Connection | unconnected | Pin 2 is not connected internally and is listed as No Connection in the datasheet pinout. |
| 3 | Cathode | passive | Cathode terminal of the Zener regulator diode; for the LBZX84C8V2LT1G (marking Z7) the nominal zener voltage is 8.2 V at IZT1 = 5 mA, with a range of 7.7 V to 8.7 V. |
