SP1001-04XTG from Littelfuse, in a SOT-553. 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 | I/O1 | passive | ESD-protected I/O line with 8pF typical capacitance, 5.5V maximum reverse standoff voltage, and ±15kV contact / ±30kV air ESD protection (IEC 61000-4-2). |
| 2 | GND | power_in | Common ground pin of the array, connected to signal/shield ground as shown in the application example. |
| 3 | I/O2 | passive | ESD-protected I/O line with 8pF typical capacitance, 5.5V maximum reverse standoff voltage, and ±15kV contact / ±30kV air ESD protection (IEC 61000-4-2). |
| 4 | I/O3 | passive | ESD-protected I/O line with 8pF typical capacitance, 5.5V maximum reverse standoff voltage, and ±15kV contact / ±30kV air ESD protection (IEC 61000-4-2). |
| 5 | I/O4 | passive | ESD-protected I/O line with 8pF typical capacitance, 5.5V maximum reverse standoff voltage, and ±15kV contact / ±30kV air ESD protection (IEC 61000-4-2). |
