LMSZ5252BT1G

LRC · Zener Diodes · SOD-123

LMSZ5252BT1G 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 on the package (Style 1 pin 1 per the SOD-123 outline drawing).
2 Anode passive Anode terminal, the terminal opposite the cathode (Style 1 pin 2 per the SOD-123 outline drawing).

CAD (KiCad official)

  • Symbol: LMSZ5252BT1G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: lmsz5252bt1g-etched.step / lmsz5252bt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lmsz5252bt1g.step / lmsz5252bt1g.glb are the bare package body.
