OVERVOLTAGE SUPPRESSION TECHNOLOGIES (1-6)
1. TVS Diodes — Suppress
overvoltage transients such
as Electrical Fast Transients
(EFT), inductive load switching
and lightning in a wide
variety of applications in the
computer, industrial, telecom
and automotive markets.
4. Gas Plasma Arrestors
(GDTs) — Available in small
footprint leaded and surface
mount conﬁgurations,
Littelfuse GDTs respond
fast to transient overvoltage
events, reducing the risk of
equipment damage.
2. Varistors — Multiple forms,
from Metal Oxide Varistors
(MOVs) that suppress transient
voltages to Multi-Layer Varistors
(MLVs) designed for applications
requiring protection from
various transients in computers
and handheld devices as well
as industrial and automotive
applications.
5. Silicon Protection
Arrays — Designed speciﬁcally
to protect analog and digital
signal lines from electrostatic
discharge (ESD) and other
overvoltage transients.
3. SIDACtor® Devices—
Complete line of protection
thyristor products speciﬁcally
designed to suppress
overvoltage transients in a
broad range of telecom and
datacom applications.

GDTs dissipate voltage transients through a contained plasma gas. They have high insulation resistance plus low capacitance and leakage to
ensure minimal effect on normal operation of equipment. Littelfuse devices offer a small footprint and are available in leaded and surface mount
conﬁgurations, with high surge handling capability. Their fast response to transient over-voltage events, and ability to dissipate large amounts
of energy, translates into reduced risk of equipment damage. The amount of energy they can dissipate makes them a good choice for lightning
surge protection, particularly for telecomm equipment located in outdoor structures.

Gas Discharge Tube (GDT) Products
AC and CG3 Series
AC and CG3 Series
®
Description
Littelfuse AC series two-electrode line protectors
provide a high degree of surge protection in AC line
applications. The two models, AC120 and AC240
are designed for use with 120VAC and 240VAC lines
respectively. They are able to extinguish AC follow-on
currents of at least 200A.
Littelfuse CG3 two electrode high voltage (1.0 - 7.5
KV) devices are designed for surge protection and
high isolation applications, and for applications
for which bias voltages or signal levels of several
hundred volts are normally present.

Description
The SL1003A series has been especially developed
GPS#SPBECBOEFRVJQNFOU4QFDJBMEFTJHOGFBUVSFT
provide high levels of protection against fast rising
transients in the 100V/μs to 1kV/μs range usually
caused by lightning disturbances.
These devices have ultra low capacitance 1.5pF and
QSFTFOUJOTJHOJmDBOUTJHOBMMPTTFTVQUP()[
These devices are extremely robust and are able to
divert a 5000A pulse without destruction. For AC
