LBZT52B20T1G

LRC · Zener Diodes · SOD-123

LBZT52B20T1G 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 of the Zener diode, identified by the polarity band on the SOD-123 body (STYLE 1: pin 1 = cathode).
2 ANODE passive Anode of the Zener diode (STYLE 1: pin 2 = anode), with the equivalent circuit showing cathode on pin 1 and anode on pin 2.

CAD (KiCad official)

  • Symbol: LBZT52B20T1G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: lbzt52b20t1g-etched.step / lbzt52b20t1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lbzt52b20t1g.step / lbzt52b20t1g.glb are the bare package body.
