SZ1SMA6.0AT3G

Littelfuse · ESD And Surge Protection (TVS/ESD) · SMA

SZ1SMA6.0AT3G from Littelfuse, in a SMA. 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 Cathode passive Cathode terminal of the uni-directional TVS; it is marked by the color band and the cathode mark on the package, and the datasheet does not give a separate electrical limit for this pin.
2 Anode passive Anode terminal of the uni-directional TVS, which clamps transients to the Zener breakdown and clamping limits listed in the electrical characteristics table.

CAD (KiCad official)

  • Symbol: SZ1SMA6.0AT3G
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: sz1sma6-0at3g-etched.step / sz1sma6-0at3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sz1sma6-0at3g.step / sz1sma6-0at3g.glb are the bare package body.
