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. |
