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.
