Lightning Surge Protection -SP4031
SP1050 Series SP4031 RoHS Pb GREEN Description
The SP4031 hybrid protector offers both overcurrent and
differential only overvoltage protection for applications such
as 10/100/1000 BaseT ports. Compliant with the newest
standards of overvoltage per industry standard ITU-T K.21.
Tested to basic tests levels 2.5kV overvoltage. Flowthrough package layout allows PCB trace routing directly
through the SP4031 without changing pitch dimensions,
thus having less impact on normal signal high frequency
components.
During a prolonged overvoltage event such as a power
fault, this component will present a high impedance. The
high impedance state will reset once the power fault event
has ended. During a fast transient event, the component
will clamp, thus protecting any downstream chipsets. Functional Block Diagram
