DDZ33CSF-7

Diodes Incorporated · Zener Diodes · SOD-323F

DDZ33CSF-7 from Diodes Incorporated, in a SOD-323F. 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, the terminal marked by the cathode band, which goes positive relative to the anode in zener breakdown (VZ 30.90V min to 32.50V max at IZT = 5mA for DDZ33CSF).
2 A passive Anode, the terminal opposite the cathode band, with forward voltage VF of 0.9V at IF = 10mA.

CAD (KiCad official)

  • Symbol: DDZ33CSF-7
  • Footprint: Diode_SMD:D_SOD-323F
  • 3D model: SOD-323F (KiCad packages3D, STEP)
  • 3D model files: ddz33csf-7-etched.step / ddz33csf-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddz33csf-7.step / ddz33csf-7.glb are the bare package body.
