Description of 3RB-8S Gas Discharge Tube
GDT
is
placed
in
front
of,
and
in
parallel
with,
sensitive
telecom
equipment
such
as
power
lines,
communication
lines,
signal
lines
and
data
transmission
lines
to
help
protect
them
from
damage
caused
by
transient
surge
voltages
that
may
result
from
lightning
strikes
and
equipment
switching
operations.
These
devices
do
not
influence
the
signal
in
normal
operation.
However,
in
the
event
of
an
overvoltage
surge,
such
as
a
lightning
strike,
the
GDT
switches
to
a
low
impedance
state
and
diverts
the
energy
away
from
the
sensitive
equipment.
Our
GDT
offer
a
high
level
of
surge
protection,
a
broad
voltage
range,
low
capacitance,
and
many
form
factors
including
new
surface
mount
devices,
which
makes
them
suitable
for
applications
such
as
Main
Distribution
Frame
(MDF)
modules,
high
data-rate
telecom
applications
(e.g.
ADSL,
VDSL),
and
surge
protection
on
power
lines.
Their
low
capacitance
also
results
in
less
signal
distortion.
When
used
in
a
coordinated
circuit
protection
solution
with
PolySwitch
devices,
they
can
help
equipment
manufacturers
meet
stringent
safety
regulatory standards.
