LBZX84C47LT1G

LRC · Zener Diodes · SOT-23

LBZX84C47LT1G 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; for LBZX84C47LT1G the datasheet gives a nominal zener voltage VZ of 47 V (min 44 V, max 50 V at IZT1 = 5 mA).
2 No Connection unconnected Pin 2 is labeled 'No Connection' in the datasheet pinout and is not electrically used in the device.
3 Cathode passive Cathode terminal of the zener regulator diode; the datasheet pin diagram places the cathode on pin 3 of the SOT-23 package.
