The SP2502L provides overvoltage protection for applications such as 10/100/1000 Base-T Ethernet and T3/ E3 interfaces. This device has a low capacitance of only 5pF making it suitable for PHY side Ethernet protection and the capability to protect against both longitudinal and differential transients. Furthermore, the SP2502L is rated up to 100A (tp=2/10μs) making it suitable for line side protection as well against lightning transients as defined by GR-1089 (intra-building), ITU, YD/T, etc. The application schematic provides the connection information for a PHY side protection scheme of a single differential pair.
