DDZX15-7

Diodes Incorporated · Zener Diodes · SOT-23

DDZX15-7 from Diodes Incorporated, in a SOT-23. 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 A passive Anode of the zener diode, the lower-left lead in the top-view device schematic.
2 NC unconnected No internal connection; the lower-right lead is not connected to the diode in the device schematic.
3 K passive Cathode of the zener diode, the single top lead in the device schematic; the DDZX15 has VZ of 14.80 to 15.57 V at IZT = 10 mA.

CAD (KiCad official)

  • Symbol: DDZX15-7
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ddzx15-7-etched.step / ddzx15-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddzx15-7.step / ddzx15-7.glb are the bare package body.
