BOURNS ® TCS ™ TRANSIENT CURRENT SUPPRESSOR WHITE PAPER

A New Circuit Protection Device for VDSL Applications
INTRODUCTION
Bourns® TCS™ Devices

Since the first electronic equipment was designed, engineers have had to deal with protecting their
equipment against electrical surges, primarily Electrostatic Discharge (ESD) and lightning.
Equipment interfaces can be exposed to a wide range of discharge events up to and including
surges caused by lightning. Even with ESD-immune optical fibers transmitting data long distances,
connection from the optical-electrical interface equipment to offices and residential buildings is still
primarily through external conventional electrical cabling, exposing this equipment to high energy
electrical surges.

Modern electronics, in the quest for ever higher speed and lower cost, use ever denser IC
technologies whose sensitivity to surges creates an increasingly difficult challenge for designers
of electronic equipment. As technology advances, conventional circuit protection solutions have
become less effective in protecting sensitive electronics from surges. Furthermore, these conventional
solutions struggle to meet the signal integrity requirements for very high-speed transmissions.
This white paper examines how the new Bourns® Transient Current Suppressor (TCS™) protection
device can meet the surge protection and transmission performance challenges of modern
communication systems.
