Description
RailClamps are surge rated diode arrays designed to
protect high speed data interfaces. The RClamp series
has been specifically designed to protect sensitive
components from overvoltage caused by ESD (electro-
static discharge), CDE (cable discharge events), EFT
(electrical fast transients), and lightning. The
RClampTM7002M has been optimized for use on the
next generation of ADSL interfaces. Their high surge
capability makes them particularly useful in systems
that utilize gas tubes as the primary protection compo-
nent.
This device integrates surge rated, low capacitance
steering diodes in a small MSOP-10L package. Each
protection diode features a large area junction to
minimize clamping voltage and increase reliability
during high current surges. It has a maximum capaci-
tance of only 10pF and may be used to protect two
high-speed lines without sacrificing signal integrity. The
RClamp7002M may be used on systems operating
from 3.3 to 70 volts. This means that they may be
used in applications that use the Central Office battery
as the main supply.
The RClamp7002M is also designed for easy board
layout by allowing the signal traces to run straight
through the device. The high surge capability, ease of
layout coupled with the low capacitance and clamping
voltage of the RClamp7002M makes it the superior
choice for protecting two high speed lines against high
energy telecommunication surges.
