SP3004-04XTG from Littelfuse, in a SOT-563. 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 rail-to-rail diodes and an additional zener, rated for ±12kV contact and ±15kV air discharge per IEC 61000-4-2 with 0.85pF typical capacitance per I/O. |
| 2 | GND | power_in | Ground reference for the rail-to-rail protection diodes. |
| 3 | I/O2 | passive | ESD-protected I/O line with rail-to-rail diodes and an additional zener, rated for ±12kV contact and ±15kV air discharge per IEC 61000-4-2 with 0.85pF typical capacitance per I/O. |
| 4 | I/O3 | passive | ESD-protected I/O line with rail-to-rail diodes and an additional zener, rated for ±12kV contact and ±15kV air discharge per IEC 61000-4-2 with 0.85pF typical capacitance per I/O. |
| 5 | VCC | power_in | Positive rail reference for the protection diodes; the application note states it can be replaced by a suitable bypass capacitor or left floating or NC in some backdrive applications. |
| 6 | I/O4 | passive | ESD-protected I/O line with rail-to-rail diodes and an additional zener, rated for ±12kV contact and ±15kV air discharge per IEC 61000-4-2 with 0.85pF typical capacitance per I/O. |
