SP4023-01FTG-C

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

SP4023-01FTG-C 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 1 passive Protected I/O line of the bidirectional TVS (-C variant), with 15V reverse standoff, 16V min breakdown at 1mA and 1.3pF typical capacitance.
2 2 passive Second terminal of the bidirectional TVS (-C variant), connected to the other line or ground, with ±30kV ESD contact/air withstand per IEC 61000-4-2 and 12A 8/20µs surge capability.
