LRC · Zener Diodes · SOT-23
LBZX84C7V5LT1G 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; for the LBZX84C7V5LT1G, the forward voltage is 0.90 V max at IF = 10 mA (TA = 25°C). |
| 2 | NC | unconnected | No connection; the datasheet lists pin 2 as No Connection for the BZX84Cxxx LT1 series. |
| 3 | Cathode | passive | Cathode of the zener diode; the LBZX84C7V5LT1G has a nominal zener voltage VZ of 7.5 V (range 7.0 V to 7.9 V at IZT1 = 5 mA) with a maximum reverse leakage of 1 µA at VR = 5 V. |
