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. Flow-through 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.
