CDSOD323-T12

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

CDSOD323-T12 from BOURNS, 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 1 passive Terminal 1 of the unidirectional TVS diode (CDSOD323-T12, no "C" suffix); VWM 12.0 V, minimum VBR 13.3 V @ 1 mA, maximum VC 19.0 V @ IP = 1 A.
2 2 passive Terminal 2 of the unidirectional TVS diode; the cathode is marked by the polarity band on the package, with 350 W peak pulse power (8/20 μs) and ESD protection up to 30 kV.

CAD (KiCad official)

  • Symbol: CDSOD323-T12
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: cdsod323-t12-etched.step / cdsod323-t12-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cdsod323-t12.step / cdsod323-t12.glb are the bare package body.
