2017 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 02/23/17 TVS Diode Arrays (SPA Diodes) TVS Diode Arrays (SPA Diodes) Lightning Surge Protection - SP2502L Series Description Applications 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=2/10s) 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.

Application Example The schematic shows protection for a single differential pair as part of a larger high-speed data interface such as Ethernet. The SP2502L provides both metallic (differential) and longitudinal (common mode) protection from lightning induced surge events as specified by regulatory standards such as Telcordia's GR-1089 CORE and ITU K.20 and 21. The SP2502L protects against both positive and negative induced surge events while the TeleLink fuse provides overcurrent protection for the long term 50/60 Hz power fault events. to chipset (Ethernet PHY, T3/E3 PHY, etc.) TeleLink (0461 1.25) SP2502L 1 2 3 4 8 7 6 5 RoHS Pb GREEN Additional Information Datasheet Samples Resources
