DDZX27D-7

Diodes Incorporated · Zener Diodes · SOT-23

DDZX27D-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, connected to the one bottom-edge terminal that the device schematic shows tied to the diode.
2 NC unconnected Bottom-edge terminal shown in the device schematic without a connection to the diode.
3 K passive Cathode of the zener diode, the single top-edge terminal in the schematic; the DDZX27D is rated VZ 26.29 to 27.64 V at IZT = 5 mA.

CAD (KiCad official)

  • Symbol: DDZX27D-7
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ddzx27d-7-etched.step / ddzx27d-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddzx27d-7.step / ddzx27d-7.glb are the bare package body.
