S-LBZX84C33LT1G

LRC · Zener Diodes · SOT-23

S-LBZX84C33LT1G 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 diode, identified as pin 1 in the SOT-23 pinout for the BZX84Cxx LT1 series.
2 NC unconnected No internal connection; the datasheet lists this pin as no connection.
3 Cathode passive Cathode terminal of the zener diode, identified as pin 3 in the SOT-23 pinout for the BZX84Cxx LT1 series.
