1.5SMC400CA

Littelfuse · TVS · DO-214AB

1.5SMC400CA from Littelfuse, in a DO-214AB. 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 A1 passive Bidirectional TVS terminal with no polarity (no cathode band), interchangeable with the other terminal; 1.5SMC400CA has VR 342 V, VBR 380-420 V at 1 mA and VC 548 V max at 3.7 A Ipp.
2 A2 passive Bidirectional TVS terminal with no polarity (no cathode band), interchangeable with the other terminal; rated for 2000 W peak pulse power (stacked-die part) at 10/1000 µs.

CAD (KiCad official)

  • Symbol: 1.5SMC400CA
  • Footprint: Diode_SMD:D_SMC
  • 3D model: DO-214AB (KiCad packages3D, STEP)
  • 3D model files: 1-5smc400ca-etched.step / 1-5smc400ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1-5smc400ca.step / 1-5smc400ca.glb are the bare package body.
