DDZX5V1B-7

Diodes Incorporated · Zener Diodes · SOT-23

DDZX5V1B-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, shown on a bottom-left pin in the device schematic; the datasheet gives VZ of 4.94V to 5.20V at IZT = 20mA for the DDZX5V1B.
2 NC unconnected No internal connection; the second bottom pin is shown unconnected in the device schematic.
3 K passive Cathode of the zener diode, shown on the single top pin in the device schematic; maximum power dissipation is 300mW on FR-4 PCB.

CAD (KiCad official)

  • Symbol: DDZX5V1B-7
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ddzx5v1b-7-etched.step / ddzx5v1b-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddzx5v1b-7.step / ddzx5v1b-7.glb are the bare package body.
