C-III Varistor Series  
Description  
The C-III 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 Series is primarily intended for use in AC  
lineTransient Voltage Surge Suppressor (TVSS)  
product environment and other similar applications  
requiring high transient energy and peak current  
capability in a relatively small package size.

Power Dissipation Ratings  
Peak Pulse CurrentTestWaveform  
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.

Radial Lead Varistors > C-III 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.

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 varistors 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.

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 80 pulses  
for the 20mm units and 40 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 100  
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.

negligible changes in any of the device characteristics after  
2000 pulses, as shown in the lower diagram at right.
