SP0402U-ELC-02ETG

Littelfuse · ESD And Surge Protection (TVS/ESD) · 0402

SP0402U-ELC-02ETG from Littelfuse, in a 0402. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IO passive Cathode of the unidirectional TVS diode; connect to the protected signal/data line. Clamps at 13 V typical at IPP=2.5 A (tp=8/20 µs) with 0.30 pF typical capacitance @ VR=0 V, 3 GHz.
2 GND passive Anode of the unidirectional TVS diode; connect to system ground. Provides the ESD discharge return path.

Provenance

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

  • Datasheet: Littelfuse datasheet (None pp, sha256 379b3c8aa3b414d9, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
