DZL4733

LGE · Zener Diodes · SOD-123FL

DZL4733 from LGE, in a SOD-123FL. 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 K passive Cathode, marked by the laser band on the package; for the DZL4733 (5.1 V nominal Zener, 4.84-5.36 V at IZT = 49 mA) this pin is positive relative to the anode in Zener regulation.
2 A passive Anode; the end opposite the laser-marked cathode band of the SOD-123FL package.

CAD (KiCad official)

  • Symbol: DZL4733
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: dzl4733-etched.step / dzl4733-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dzl4733.step / dzl4733.glb are the bare package body.
