LMBZ5231BLT1G

LRC · Zener Diodes · SOT-23

LMBZ5231BLT1G 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; the datasheet pinout is 1-Anode, 2-No Connection, 3-Cathode.
2 NC unconnected Listed as No Connection in the datasheet pinout, so it has no electrical function on this device.
3 Cathode passive Cathode terminal of the Zener diode, identified on the package by the polarity band; the datasheet pinout is 1-Anode, 2-No Connection, 3-Cathode.

CAD (KiCad official)

  • Symbol: LMBZ5231BLT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: lmbz5231blt1g-etched.step / lmbz5231blt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lmbz5231blt1g.step / lmbz5231blt1g.glb are the bare package body.
