SP03A-3.3 Series
SP03A-3.3
Lightning Surge Protection - SP03A-3.3 Series
Description
Features
Applications
This SP03A 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 SP03A
is rated for GR-1089, intra-building transient immunity
requirements for telecommunication installations.

Not Intended for Use in Life Support or Life Saving Applications
The products shown herein are not designed for use in life sustaining or life saving
applications unless otherwise expressly indicated.
Application Example
This schematic shows a high-speed data interface
protection solution. The SP03A-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.
