C-III Varistor Series
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.

NOTES:
- Average power dissipation of transients not to exceed 0.6W and 1W for model sizes 14mm and 20mm, respectively.
- 7mm parts also available-contact factory for further information
- For additional or intermediary voltage ratings contact factory
Phenolic Coating Option -- C-III SeriesVaristors for Hi-Temperature Operating Conditions:
•
•
•
Phenolic Coated CIII Series devices are available with improved maximum operating maximum temperature 125ºC
These devices also have improved temperature cycling performance capability.
Ratings and Specifications are as per standard except Hi–Pot
Encapsulation (Isolation Voltage Capability)=500V.
•

Metal-OxideVaristors (MOVs)
Radial Lead Varistors > C-III Varistor Series
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 SpecificationsTable 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-OxideVaristors (MOVs)
Radial Lead Varistors > C-III Varistor Series
AC Bias Reliability
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.

at Rated Bias

V130LA20C

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.

Transient Surge Current/EnergyTransient Capability
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 powder and
improved control over the sintering and assembly
processes are contributing factors to this improvement.

C-III Series MOVs

V130LA20C
3kA (8/20μs)
In the low power AC mains environment, industry
standards (UL, IEC, NEMA and IEEE) all suggest that the
worst case surge occurrence will be 3kA. Such a transient
event may occur up to five times over the equipment life
time (approximately 10 years). While the occurences of
five 3kA transients is the required capability, the rated,
repetitive surge current for the C-III Series is 20 pulses
for the 20mm units and 10 pulses for the 14mm Series.

As a measure of the inherent device capability, samples
of the 20mm V130LA20C devices were subjected to
a worst case repetitive transient surges test. After 20
pulses, each of 3kA, there was negligible change in
the device characteristics. Changes in the clamping
voltage, measured at 100A, of less than 3% were
recorded, as shown in the upper diagram at right.
