Littelfuse · TVS · SOD-882
SP3031-01ETG from Littelfuse, in a SOD-882. 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 | Pin 1 is one of the two terminals of the single-channel unidirectional 0.8pF ESD diode, and the datasheet marks it with the Pin 1 indicator on the package drawing. |
| 2 | 2 | passive | Pin 2 is the other terminal of the single-channel unidirectional 0.8pF ESD diode, rated for ±10kV contact and ±15kV air discharge per IEC 61000-4-2. |
