SD03CQ-7

Diodes Incorporated · ESD And Surge Protection (TVS/ESD) · SOD-323

SD03CQ-7 from Diodes Incorporated, in a SOD-323. 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 PIN1 passive Bidirectional TVS terminal 1 (no polarity); protects against ESD per IEC 61000-4-2 ±30kV air/contact, VRWM 3.3V max, VBR 4.0V min at 1mA.
2 PIN2 passive Bidirectional TVS terminal 2 (no polarity); clamps to 11V max at IPP = 55A (8/20µs) in either direction relative to Pin 1.

CAD (KiCad official)

  • Symbol: SD03CQ-7
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: sd03cq-7-etched.step / sd03cq-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sd03cq-7.step / sd03cq-7.glb are the bare package body.
