SD12C.TCT

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

SD12C.TCT from SEMTECH, 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 Bidirectional TVS terminal for the protected line (SD12C: 12V reverse stand-off); device is symmetrical with no cathode band, so pins 1 and 2 are interchangeable.
2 2 passive Bidirectional TVS terminal, connected to ground or the other side of the protected line (SD12C: 12V reverse stand-off); device is symmetrical with no cathode band.

CAD (KiCad official)

  • Symbol: SD12C.TCT
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: sd12c-tct-etched.step / sd12c-tct-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sd12c-tct.step / sd12c-tct.glb are the bare package body.
