SP4044-04ATG

Littelfuse · TVS · MSOP-10

SP4044-04ATG from Littelfuse, in a MSOP-10. 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/O 1 passive ESD/surge-protected I/O channel 1 with 1.5pF (TYP) capacitance to GND, rated for 24A (8/20μs) and ±30kV IEC 61000-4-2 contact/air.
2 NC unconnected No connection.
3 GND power_in Ground reference, internally connected to pin 8 as the common return for all diode channels.
4 NC unconnected No connection.
5 I/O 2 passive ESD/surge-protected I/O channel 2 with 1.5pF (TYP) capacitance to GND, rated for 24A (8/20μs) and ±30kV IEC 61000-4-2 contact/air.
6 NC unconnected No connection.
7 I/O 3 passive ESD/surge-protected I/O channel 3 with 1.5pF (TYP) capacitance to GND, rated for 24A (8/20μs) and ±30kV IEC 61000-4-2 contact/air.
8 GND power_in Ground reference, internally connected to pin 3 as the common return for all diode channels.
9 I/O 4 passive ESD/surge-protected I/O channel 4 with 1.5pF (TYP) capacitance to GND, rated for 24A (8/20μs) and ±30kV IEC 61000-4-2 contact/air.
10 NC unconnected No connection.
