DZL4734

LGE · Zener Diodes · SOD-123FL

DZL4734 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 SOD-123FL body; DZL4734 is the 4.3 V nominal (4.08 to 4.52 V at IZT = 58 mA) zener.
2 A passive Anode, the terminal opposite the cathode band; power dissipation is rated 1.0 W and junction temperature 150 °C.

CAD (KiCad official)

  • Symbol: DZL4734
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: dzl4734-etched.step / dzl4734-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dzl4734.step / dzl4734.glb are the bare package body.
