DDZ9V1ASF-7

Diodes Incorporated · Zener Diodes · SOD-323F

DDZ9V1ASF-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 terminal, marked by the cathode band; the zener voltage VZ is measured at IZT with this pin reverse-biased positive (DDZ9V1A: 8.29V to 8.73V at 20mA... see datasheet table).
2 A passive Anode terminal, opposite the cathode band; forward voltage is 0.9V at IF = 10mA.

CAD (KiCad official)

  • Symbol: DDZ9V1ASF-7
  • Footprint: Diode_SMD:D_SOD-323F
  • 3D model: SOD-323F (KiCad packages3D, STEP)
  • 3D model files: ddz9v1asf-7-etched.step / ddz9v1asf-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddz9v1asf-7.step / ddz9v1asf-7.glb are the bare package body.
