CMOZ1L8 TR PBFREE

Central Semicon · Zener Diodes · SOD-523

CMOZ1L8 TR PBFREE from Central Semicon, in a SOD-523. 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; for CMOZ1L8 VZ is 1.71 V min, 1.8 V nominal, 1.89 V max at IZT=250 μA.
2 A passive Anode of the zener diode; forward voltage is 0.9 V max at IF=10 mA.

CAD (KiCad official)

  • Symbol: CMOZ1L8 TR PBFREE
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: cmoz1l8-tr-pbfree-etched.step / cmoz1l8-tr-pbfree-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cmoz1l8-tr-pbfree.step / cmoz1l8-tr-pbfree.glb are the bare package body.
