LBZX84C3V3LT1G

LRC · Zener Diodes · SOT-23

LBZX84C3V3LT1G 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 BZX84C3V3LT1G zener diode; the datasheet pinout lists pin 1 as Anode for the SOT-23 package.
2 NC unconnected No internal connection; the datasheet pinout states pin 2 is No Connection.
3 Cathode passive Cathode terminal of the zener diode, which regulates at a nominal VZ of 3.3 V at IZT = 5 mA per the electrical table for the LBZX84C3V3LT1G.

CAD (KiCad official)

  • Symbol: LBZX84C3V3LT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: lbzx84c3v3lt1g-etched.step / lbzx84c3v3lt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lbzx84c3v3lt1g.step / lbzx84c3v3lt1g.glb are the bare package body.
