Description
This LC03-3.3 series provides overvoltage protection for
applications such as 10/100/1000 BaseT Ethernet, and
T3/E3 interfaces. 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 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
and the LC03-3.3 is rated for GR-1089, intra-building
transient immunity requirements for telecommunication
installations.

This schematic shows a high-speed data interface
protection solution. The LC03-3.3BTG is compatible with
the intra-building surge requirements of Telcordia’s GR-
1089-CORE, and the Basic Level Recommendations of
ITU K.20 and K.21. The TeleLink fuse provides overcurrent
protection for the long term 50/60 Hz power fault events.
