Description

The SP4031 hybrid protector offers both overcurrent and

differential only overvoltage protection for applications such

as 10/100/1000BaseT 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.

These components can safely absorb up to 35A per IEC

61000-4-5 2nd edition (tp=8/20μs) without performance

degradation and a minimum ±30kV ESD per IEC 61000-4-

2 International Standard. The low loading capacitance and

high surge capability makes the SP4031 ideal for protecting

telecommunication ports such as Ethernet and other high

speed data interfaces.
