LMSZ5232BT1G

LRC · Zener Diodes · SOD-123

LMSZ5232BT1G 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 of the Zener voltage regulator; the datasheet pin figure identifies pin 1 as cathode for the SOD-123 package.
2 Anode passive Anode terminal of the Zener voltage regulator; the datasheet pin figure identifies pin 2 as anode, and the forward voltage is VF ≤ 0.9 V at IF = 10 mA.

CAD (KiCad official)

  • Symbol: LMSZ5232BT1G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: lmsz5232bt1g-etched.step / lmsz5232bt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lmsz5232bt1g.step / lmsz5232bt1g.glb are the bare package body.
