LBZT52B18T1G

LRC · Zener Diodes · SOD-123

LBZT52B18T1G from LRC, in a SOD-123. 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 CATHODE passive Cathode terminal, identified by the polarity band; the datasheet gives it as the cathode of the Zener diode with a 500 mW total power dissipation rating for the device.
2 ANODE passive Anode terminal of the Zener diode, opposite the polarity-band cathode (pin 1).

CAD (KiCad official)

  • Symbol: LBZT52B18T1G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: lbzt52b18t1g-etched.step / lbzt52b18t1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lbzt52b18t1g.step / lbzt52b18t1g.glb are the bare package body.
