Lightning Surge Protection - SP03-6 Series
Description
Features
Applications
This new broadband protection device from Littelfuse
provides overvoltage protection for applications such
as 10/100/1000 BaseT Ethernet, T3/E3 DS3 interfaces,
ADSL2+, and VDSL2+. This new protector combines the
TVS diode element with a diode rectifier bridge to provide
both longitudinal and differential protection in one package.
This design innovation results in a capacitive loading
characteristic that is log-linear with respect to the signal
voltage across the device. This reduces intermodulation
(IM) distortion caused by a typical solid-state protection
solution. The application schematic provides the
connection information.

Application Example
This schematic shows a high-speed data interface
protection solution. The SP03-6 provides both metallic
(differential) and longitudinal (common mode) protection
from lightning induced surge events. Its surge rating is
compatible with the intra-building surge requirements
of Telcordia’s GR-1089-CORE, and the Basic Level
Recommendations of ITU K.20 and .21. This device
protects against both positive and negative induced surge
events. The TeleLink fuse provides overcurrent protection
for the long term 50/60 Hz power fault events.
