DDZ12BQ-7

Diodes Incorporated · Zener Diodes · SOD-123

DDZ12BQ-7 from Diodes Incorporated, in a SOD-123. 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, identified by the cathode band on the SOD123 package; DDZ12B has VZ of 11.44 V to 12.03 V at IZT = 10 mA.
2 A passive Anode terminal, the end opposite the cathode band; forward voltage is 0.9 V at IF = 10 mA.

CAD (KiCad official)

  • Symbol: DDZ12BQ-7
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: ddz12bq-7-etched.step / ddz12bq-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddz12bq-7.step / ddz12bq-7.glb are the bare package body.
