DDZ20DSF-7

Diodes Incorporated · Zener Diodes · SOD-323F

DDZ20DSF-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, identified by the cathode band; for DDZ20DSF the zener voltage is 19.72 V to 20.72 V at IZT = 5 mA.
2 A passive Anode; the device is rated 500 mW power dissipation on FR-4 PCB and forward voltage 0.9 V at IF = 10 mA.

CAD (KiCad official)

  • Symbol: DDZ20DSF-7
  • Footprint: Diode_SMD:D_SOD-323F
  • 3D model: SOD-323F (KiCad packages3D, STEP)
  • 3D model files: ddz20dsf-7-etched.step / ddz20dsf-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddz20dsf-7.step / ddz20dsf-7.glb are the bare package body.
