Metal-Oxide Varistors (MOVs)
Introduction to Overvoltage Suppression
To assure reliable operation, transient voltage suppression
should be considered at early stages of the design process.
This can be a complex task as electronic components are
increasingly sensitive to stray electrical transients. The
designer must define the types of transient threats and
determine what applications are needed while meeting the
product agency norms and standards.
Varistors are increasingly used as the front-line solution for
transient surge protection. Littelfuse provides expertise
to the designer and offers the broadest range of circuit
protection technologies to choose from.
Littelfuse varistors are available in a variety of forms to
serve a wide range of applications. Options include ultra
small surface mount multi-layer suppressor (MLV) devices
for small electronics applications, and traditional midrange metal-oxide (MOV) radial and axial leaded devices
for protection of small machinery, power sources and
components. Littelfuse also offers larger terminal mount
MOVs for industrial applications.
A more recent innovation to the the Littelfuse product
line, MLVs address a specific part of the transient
voltage spectrum – the circuit board level environment
where, although lower in energy, transients from ESD,
inductive load switching, and even lightning surge
remnants would otherwise reach sensitive integrated
circuits. Each of these events can relate to a product’s
ElectroMagnetic Compatibility (EMC), or its immunity to
transients that could cause damage or malfunction.
Littelfuse offers five distinct versions of MLVs including
the MHS Series ESD Suppressor for high data rates, the
ML Series which supports the broadest application range,
the MLE Series intended for ESD while providing filter
functions, the MLN Series Quad Array in a 1206 & 0805
chip and the AUML Series characterized for the specific
transients found in automotive electronic systems.
This catalog and design guide includes selection tables,
technology tutorials, and detailed product technical
information, to aid you in choosing the correct Littelfuse
Varistor to serve your application.

Metal-Oxide Varistors (MOVs)
Introduction to Overvoltage Suppression (continued)
Transient Threats – What Are Transients?
Repeatable transients are frequently caused by the
operation of motors, generators, or the switching of
reactive circuit components. Random transients, on the
other hand, are often caused by Lightning (Figure 1) and
Electrostatic Discharge (ESD) (Figure 2). Lightning and ESD
generally occur unpredictably, and may require elaborate
monitoring to be accurately measured, especially if induced
at the circuit board level. Numerous electronics standards
groups have analyzed transient voltage occurrences
using accepted monitoring or testing methods. The key
characteristics of several transients are shown below in
Table 1.

Lead (Pb) Soldering Recommendations
Wave soldering is the most strenuous of the processes.
To avoid the possibility of generating stresses due to
thermal shock, a preheat stage in the soldering process
is recommended, and the peak temperature of the solder
process should be rigidly controlled.
When using a reflow process, care should be taken to
ensure that the SM20 chip is not subjected to a thermal
gradient steeper than 4 degrees per second; the ideal
gradient being 2 degrees per second. During the soldering
process, preheating to within 100 degrees of the solder's
peak temperature is essential to minimize thermal shock.
Once the soldering process has been completed, it is
still necessary to ensure that any further thermal shocks
are avoided. One possible cause of thermal shock is hot
printed circuit boards being removed from the solder
process and subjected to cleaning solvents at room
temperature. The boards must be allowed to cool gradually
to less than 50ºC before cleaning.

NOTE: If pulse ratings are exceeded, a shift of VN(DC)(at specified current) of
more then +/-10% could result. This type of shift, which normally results in a
decrease of VN(DC), may result in the device not meeting the original published
specifications, but does not prevent the device from continuing to function,
and to provide ample protection.

UltraMOV® Varistor Series
RoHS
Description
The UltraMOV® Metal Oxide Varistor Series is designed for
applications requiring high peak surge current ratings and
high energy absorption capability. UltraMOV® varistors are
primarily intended for use in AC Line Voltage applications
such as Surge Protection Device (SPD), Uninterruptable
Power Supplies (UPS), AC Power Taps, AC Power Meters,
or other products that require voltage clamping of high
transient surge currents from sources such as lightning,
inductive load switching, or capacitor bank switching.
These devices are produced in radial lead package
sizes of 7, 10,14 and 20mm and offered in a variety of
lead forms. UltraMOV® varistor are manufactured with
recognized epoxy encapsulation and are rated for ambient
temperatures up to 85ºC with no derating. This Series is
LASER-branded and is supplied in bulk, ammo pack (fanfold), or tape and reel packaging.

NOTE: 1. Average power dissipation of transients should not exceed 0.25W, 0.4W, 0.6W and 1.0W for 7mm, 10mm, 14mm, and 20mm model sizes, respectively.
Current Energy and Power Dissipation Ratings
device. The operating values of a MOV need to be derated
at high temperatures as shown above. Because varistors
only dissipate a relatively small amount of average power
they are not suitable for repetitive applications that involve
substantial amounts of average power dissipation.
Should transients occur in rapid succession, the average
power dissipation is the energy (watt-seconds) per pulse
times the number of pulses per second. The power so
developed must be within the specifications shown on the
Device Ratings and Specifications Table for the specific

Metal-Oxide Varistors (MOVs)
Radial Lead Varistors > C-III Varistor Series
C-III Varistor Series
RoHS
Description
The C-III Varistor Series of Metal-Oxide Varistors (MOVs)
are specifically designed for applications requiring high
surge energy absorption ratings and superior multiple
pulse absorption rating. This is achieved through a special
dielectric material formulation which also results in
higher repetitive surge ratings than other MOV types.
The C-III Varistor Series is primarily intended for use in
AC line Surge Protection Device (SPD) product and other
similar applications requiring high transient energy and
peak current capability in a relatively small package size.

Current Energy and Power Dissipation Ratings
Should transients occur in rapid succession, the average
power dissipation is the energy (watt-seconds) per pulse
times the number of pulses per second. The power so
developed must be within the specifications shown on the
Device Ratings and Specifications Table for the specific
device. The operating values of a MOV need to be derated
at high temperatures as shown above. Because varistors
only dissipate a relatively small amount of average power
they are not suitable for repetitive applications that involve
substantial amounts of average power dissipation.

Metal-Oxide Varistors (MOVs)
Radial Lead Varistors > C-III Varistor Series
AC Bias Reliability
Because of this possibility, an extensive series of
statistically designed tests were performed to determine
the reliability of the C-III type of varistor under AC bias
combined with high levels of temperature stress. To
date, this test has generated over 50,000 device hours of
operation at a temperature of 125ºC, although only rated at
85ºC. Changes in the nominal varistor voltage, measured at
1mA, of less than 2% have been recorded, as displayed in
the diagram at right.
High Temperature Operating Life 125ºC for 1000 Hours
at Rated Bias
300
V130LA20C
VNOM AT 1mA (V)
The C-III Series MOVs were designed for use on the AC
line. The varistor is connected across the AC line and is
biased with a constant amplitude sinusoidal voltage. It
should be noted that the definition of failure is a shift in the
nominal varistor voltage (VN) exceeding +/-10%. Although
this type of varistor is still functioning normally after this
magnitude of shift, devices at the lower extremities of VN
tolerance will begin to dissipate more power.

The transient surge rating serves as an excellent figure
of merit for the C-III varistor. This inherent surge handling
capability is one of the C-III varistor’s best features.
The enhanced surge absorption capability results from
improved process uniformity and enhanced construction.

The homogeneity of the raw material

Current Energy and Power Dissipation Ratings
device. The operating values of a MOV need to be derated
at high temperatures as shown above. Because varistors
only dissipate a relatively small amount of average power
they are not suitable for repetitive applications that involve
substantial amounts of average power dissipation.
Should transients occur in rapid succession, the average
power dissipation is the energy (watt-seconds) per pulse
times the number of pulses per second. The power so
developed must be within the specifications shown on the
Device Ratings and Specifications Table for the specific

Current Energy and Power Dissipation Ratings
device. The operating values of a MOV need to be derated
at high temperatures as shown above. Because varistors
only dissipate a relatively small amount of average power
they are not suitable for repetitive applications that involve
substantial amounts of average power dissipation.
Should transients occur in rapid succession, the average
power dissipation is the energy (watt-seconds) per pulse
times the number of pulses per second. The power so
developed must be within the specifications shown on the
Device Ratings and Specifications Table for the specific

NOTE: If pulse ratings are exceeded, a shift of VN(DC)(at specified current) of
more then +/-10% could result. This type of shift, which normally results in a
decrease of VN(DC), may result in the device not meeting the original published
specifications, but does not prevent the device from continuing to function,
and to provide ample protection.

Additional Information
These varistors have similar package construction but differ
in size and ratings. The BA models are rated from 130 to
880VM(AC). The BB models from 1100 to 2800VM(AC).
Both the BA and BB Series feature improved creep and
strike capability to minimize breakdown along the package
surface, a package design that provides complete electrical
isolation of the disc subassembly, and rigid terminals to
ensure secure wire contacts.

Should transients occur in rapid succession, the average power
dissipation required is simply the energy (watt-seconds) per pulse
times the number of pulses per second. The power so developed
must be within the specifications shown on the Device Ratings
and Characteristics Table for the specific device. Furthermore,
the operating values need to be derated at high temperatures as
shown in the above diagram. Because varistors can only dissipate
a relatively small amount of average power they are, therefore, not
suitable for repetitive applications that involve substantial amounts
of average power dissipation.

Should transients occur in rapid succession, the
average power dissipation required is simply the energy
(watt- seconds) per pulse times the number of pulses
per second. The power so developed must be within
the specifications shown on the Device Ratings and
Specifications table for the specific device. Furthermore,
the operating values need to be derated at high
temperatures as shown above. Because varistors can only
dissipate a relatively small amount of average power they
are, therefore, not suitable for repetitive applications that
involve substantial amounts of average power dissipation.

Should transients occur in rapid succession, the average power
dissipation required is simply the energy (watt-seconds) per
pulse times the number of pulses per second. The power
so developed must be within the specifications shown on
the Device Ratings and Specifications table for the specific
device. Furthermore, the operating values need to be derated
at high temperatures as shown in above. Because varistors
can only dissipate a relatively small amount of average power
they are, therefore, not suitable for repetitive applications that
involve substantial amounts for average power dissipation.

RoHS
Description
The HB34, HF34, and HG34 Series of transient surge
suppressors are industrial high-energy Metal-Oxide
Varistors (MOVs). They are designed to provide surge
suppression in the AC mains outdoor and service entrance
environment (distribution panels) of buildings. Applications
also include industrial heavy motors, controls, and power
supplies such as used in the oil-drilling, mining, and
transportation fields, including HVAC and motor/generator
applications.

The HB34 Series provides rigid terminals for throughhole solder mounting on printed circuit boards, thereby
eliminating the need for screw mounting. The HF34
Series has the same rigid through-hole terminals as the
HB34 with the addition of mounting holes for bolt-down
mounting and longer terminals to allow for additional
mounting flexibility. The HG34 has formed feet with
mounting holes for vertical bolt-down mounting.

Should transients occur in rapid succession, the
average power dissipation result is simply the energy
(watt-seconds) per pulse times the number of pulses
per second. The power so developed must be within
the specifications shown on the Device Ratings and
Specifications Table for the specific device. The operating
values must be derated as shown in above.

NOTE: If pulse ratings areHB34,

a shift
VN(DC) (at specified current) of more than
+/-10% could result. This type of shift, which normally results in a decrease of VN(DC), may
result in the device not meeting the original published specifications, but it does not
prevent the device from continuing to function, and to provide ample protection.

Metal-Oxide Varistors (MOVs)
Industrial High Energy Terminal Varistors > DHB34 Series
DHB34 Varistor Series
RoHS
Description
The DHB34 Series of transient surge suppressors is
comprised of two industrial high-energy Metal-Oxide
Varistors (MOVs) discs placed in parallel as a single device.
They are designed to provide surge suppression in the
AC mains outdoor and service entrance environment
(distribution panels) of buildings. DHB34 applications
also include industrial heavy motors, controls, and power
supplies such as used in the oil-drilling, mining, and
transportation fields, including HVAC and motor/generator
applications.
The DHB34 Series provides rigid terminals for throughhole solder mounting on printed circuit boards, thereby
eliminating the need for screw mounting.

NOTE: If pulse ratings are
exceeded, a- shift
of VN(DC) (at specified current) of more than
+/-10% could result. This type of shift, which normally results in a decrease of VN(DC), may
result in the device not meeting the original published specifications, but it does not
prevent the device from continuing to function, and to provide ample protection.

Metal-Oxide Varistors (MOVs)
High Energy Industrial Disc Varistors > CA Series
CA Varistor Series
Description
The CA Series of transient surge suppressors are industrial
high-energy disc varistors (MOVs) intended for special
applications requiring unique electrical contact or packaging
methods provided by the customer. The electrode finish
of these devices is solderable and can also be used with
pressure contacts. Discs of the same diameter may be
stacked.
This series of industrial disc varistors are nominal 60mm
diameter, with disc thickness ranging from 2.7mm to
32mm. The voltage range is 250V to 2800 V(AC)RMS.
For information on soldering considerations, refer to EC637
"Recommendations for Soldering Terminal Leads to MOV
Varistor Discs."

dissipation result is the energy (watt-seconds) per pulse times
the number of pulses per second. The power so developed must
be within the specifications shown on the Device Ratings and
Specifications table for the specific device. Furthermore, the
operating values need to be derated at high temperatures as
shown in above. Because varistors can only dissipate a relatively
small amount of average power they are, therefore, not suitable
for repetitive applications that involve substantial amounts of
average power dissipation.

NOTE: If pulse ratings are exceeded, a shift of VN(DC) (at specified current) of more than
+/-10% could result. This type of shift, which normally results in a decrease of VN(DC), may
result in the device not meeting the original published specifications, but does not prevent
the device from continuing to function, and to provide ample protection.

dissipation required
is simply the energy (watt-seconds) per
pulse times the number of pulses per second. The power so
developed must be within the specifications shown on the
Device Ratings and Specifications table for the specific device.
Furthermore, the operating values need to be derated at high
temperatures as shown above. Because varistors can only
dissipate a relatively small amount of average power they are,
therefore, not suitable for repetitive applications that involve
substantial amounts of average power dissipation.

NOTE: If pulse ratings are exceeded, a shift of VN(DC) (at specified current) of more than
+/-10% could result. This type of shift, which normally results in a decrease of VN(DC), may
result in the device not meeting the original published specifications, but it does not
prevent the device from continuing to function, and to provide ample protection.

Metal-Oxide Varistors (MOVs)
High Reliability Varistors
Radiation Hardness
For space applications, an extremely important property of a
protection device is its response to imposed radiation effects.
Electron Irradiation
A Littelfuse MOV and a Silicon transient suppression diode
were exposed to electron irradiation. The V-I curves, before
and after test, are shown below.

apparent that the Littelfuse MOV was virtually unaffected,
even at the extremely high dose of 108 rads, while the
Silicon transient suppression diode showed a dramatic
increase in leakage current.
Neutron Effects
A second MOV-Zener comparison was made in response to
neutron fluence. The selected devices were equal in area.
Figure 2 shows the clamping voltage response of the MOV
and the Zener to neutron irradiation to as high as 1015 N/
cm2. It is apparent that in contrast to the large change in
the Zener, the MOV is unaltered. At highercurrents where
the MOV’s clamping voltage is again unchanged, the Zener
device clamping voltage increases by as much as 36%.

FIGURE 3. V-I CHARACTERISTIC OF PN-JUNCTION
At low reverse voltage, the device will conduct very little
current (the saturation current). At higher reverse voltage
VBO (breakdown voltage),the current increases rapidly as
the electrons are either pulled by the electric field (Zener
effect) or knocked out by other electrons (avalanching). A
further increase in voltage causes the device to exhibit a
negative resistance characteristic leading to secondary
breakdown.
This manifests itself through the formation of hotspots,
and irreversible damage occurs. This failure threshold
decreases under neutron irradiation for Zeners, but not for
ZNO Varistors.

The solid and open circles for a given fluence represent the
high and low breakdown currents for the sample of devices
tested. Note that there is a marked decrease in current (or
energy) handling capability with increased neutron fluence.
Failure threshold of Silicon semiconductor junctions is
further reduced when high or rapidly increasing currents
are applied. Junctions develop hot spots, which enlarge
until a short occurs if current is not limited or quickly
removed.

Counterclockwise rotation of the V-I characteristics is

Description
The Littelfuse TMOV® and iTMOV® thermally protected
varistors represent a new development in integrated
circuit protection. Both versions are comprised of radial
leaded Metal Oxide Varistors (MOVs) with an integrated
thermally activated element designed to open in the
event of overheating due to the abnormal overvoltage,
limited current, conditions outlined in UL1449. The TMOV®
and iTMOV® varistor’s integrated thermal element, in
conjunction with appropriate enclosure design, helps
facilitate SPD module compliance to UL1449 for both cord
connected and permanently connected applications.

Additional Information
The TMOV® and iTMOV® varistors offer quick thermal
response due to the close proximity of the integrated
thermal element to the MOV body. The integrated
configuration also offers lower inductance than most
discrete solutions resulting in improved clamping
performance to fast overvoltage transients.
The iTMOV® varistor differs from the TMOV® varistor by the
inclusion of a third lead for the purpose of indicating that
the MOV has been disconnected from the circuit. This lead
facilitates connection to monitoring circuitry.
Additionally TMOV® and iTMOV® varistors are wave
solderable, thus simplifying end product assembly by
reducing the the expense and rework associated with hand
soldering operations.

Wave Solder Profile
Because the TMOV® and iTMOV® varistors contain a thermal protection device, care must be taken when soldering the devices into place.
Two soldering methods are possible. Firstly, hand soldering: It is recommended to heat-sink the leads of the device. Secondly, wave soldering: It is critically important that all preheat stage and the solder bath temperatures are rigidly controlled.

Metal-Oxide Varistors (MOVs)
Radial Lead Varistors > TMOV®25S Varistor Series
TMOV®25S Varistor Series
RoHS
Description
Metal Oxide Varistors (MOVs) are rated for specific AC line
operating voltages, and exceeding these limits through the
application of a sustained abnormal over-voltage condition
could result in overheating and damage to the MOV.
The Littelfuse TMOV®25S Varistor Series was designed to
address this condition in a single integrated package.
The TMOV®25S Varistor Series incorporates a patented
integrated thermally responsive element within the body
of the device which will open-circuit the varistor in case of
overheating due to the abnormal over-voltage events.

Wave Solder Profile
Because the TMOV®25S Varistor Series contains a
thermally responsive device, care must be taken when
soldering the device into place. Two soldering methods
are possible. Firstly, hand soldering: We recommend
the use of pliers to heat-sink the leads of the device.
Secondly, wave-soldering: This is a strenuous process
requiring pre-heat stages to reduce the stresses on
devices.
It is critically important that all preheat stage and the
solder bath temperatures are rigidly controlled. The
recommended solder for the TMOV® Varistor Series
is a 62/36/2 (Sn/Pb/Ag), 60/40 (Sn/Pb) or 63/37 (Sn/
Pb). Littelfuse also recommends an RMA solder flux.
SAC solders (SnAgCu) are recommended for Lead-free
applications.

TMOV®34S Varistor Series
RoHS
Description
The Littelfuse TMOV®34S thermally protected varistor
series consists of a 34mm square format varistor element
(MOV) with an integral thermally activated element. This
element is designed to open in the event of overheating
due to abnormal overvoltage, limited current conditions.
Certain TMOV®34S varistor are offered with a "monitor"
lead which may be connected to signalling circuity to
indicate if the MOV has been disconnected from the circuit.
TMOV®34S varistor series offer quick thermal response due
to the close proximity of the integrated thermal element
to the MOV body. The integrated configuration also offers
lower inductance than most discrete solutions resulting
in improved clamping performance to fast over voltage
transients.

Thermally Protected Varistors > SMOV®25S Varistor Series
SMOV25S® Varistor Series
RoHS
Description
The Littelfuse SMOV®25S thermally protected varistor is a
self-protected device. It consists of a 25mm square varistor
with an integral thermal disconnect designed to open in the
event of overheating due to abnormal overvoltage as outlined
in UL1449. The SMOV® helps facilitate SPD module compliance
to UL1449 and offers quick thermal response due to the close
proximity of the integrated thermal element to the MOV body.
This configuration also offers lower inductance than most discreet
solutions resulting in improved clamping performance to fast over
voltage transients.
The device has a separate micro-switch, which can be used to
indicate that the MOV has been disconnected from the circuit. This
separate switch makes the monitoring circuitry completely isolated
from the main power which ensures indicator circuit safety and
simplifies the customers circuit design.

Thermally Protected Varistors > SMOV®34S Varistor Series
SMOV®34S Varistor Series
RoHS
Description
The Littelfuse SMOV®34S thermally protected varistor is a
self-protected device. It consists of a 34mm square varistor
with an integral thermal disconnect designed to open in the
event of overheating due to abnormal overvoltage as outlined
in UL1449. The SMOV® helps facilitate SPD module compliance
to UL1449 and offers quick thermal response due to the close
proximity of the integrated thermal element to the MOV body.
This configuration also offers lower inductance than most discreet
solutions resulting in improved clamping performance to fast over
voltage transients.
The device has a separate micro-switch, which can be used to
indicate that the MOV has been disconnected from the circuit. This
separate switch makes the monitoring circuitry completely isolated
from the main power which ensures indicator circuit safety and
simplifies the customers circuit design.

Because the SMOV®34S varistors contain a thermal protection
device, care must be taken when soldering the devices into place.
Two soldering methods are possible. Firstly, hand soldering: It is
recommended to heat–sink the leads of the device. Secondly,
wave–soldering: It is critically important that all preheat stage and
the solder bath temperatures are rigidly controlled.

Metal-Oxide Varistors (MOVs)
Industrial High Energy Terminal Varistors > FBMOV Series
FBMOV Varistor Series
RoHS
Description
The Littelfuse FBMOV Series thermally protected and
non-fragmenting varistor represents a new development
in circuit protection. It consists of a 40kA varistor building
block (MOV) with an integral thermally activated element
designed to open in the event of overheating due to
abnormal over-voltage, limited current conditions.
FBMOV series devices also include a varistor series fuse
which prevents the part from rupturing when subjected to
high fault current (up to 200kA).The tubular fuse-like body
allows for easy mechanical connection in the application.
Another feature of FBMOV is an indicator lead, which may
be connected to monitoring circuitry and used to signal if
the MOV has been disconnected.
Applications
• Type 1 SPD (Surge Protection Device) Products
FBMOV series devices offer quick thermal response due
to the close proximity of the integrated fusing thermal
element to the MOV body. The integrated configuration
also offers lower inductance than most discreet solutions
resulting in improved clamping performance to fast overvoltage transients.
