SD12-01FTG

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

SD12-01FTG from Littelfuse, 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 Pin 1 passive Terminal 1 of the unidirectional SD12 TVS diode (12.0V reverse standoff, 450W 8/20μs peak pulse power), marked as Pin 1 in the package drawing and the tape orientation.
2 Pin 2 passive Terminal 2 of the unidirectional SD12 TVS diode (12.0V reverse standoff, 450W 8/20μs peak pulse power), marked as Pin 2 in the package drawing.

CAD (KiCad official)

  • Symbol: SD12-01FTG
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: sd12-01ftg-etched.step / sd12-01ftg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sd12-01ftg.step / sd12-01ftg.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
