Varistor Products Radial Lead Varistors > C-III series RoHS 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 line Transient Voltage Surge Suppressor (TVSS) product environment and other similar applications requiring high transient energy and peak current capability in a relatively small package size.

Varistor Products 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 (V/) exceeding +/-10%. Although this type of varistor is still functioning normally after this magnitude of shift, devices at the lower extremities of V/ tolerance will begin to dissipate more power. High Temperature Operating Life 125ºC for 1000 Hours at Rated Bias 300 VNOM AT 1mA (V) 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. 250 200 150 100 0 100 200 300 Figure 12 400 500 600 700 TIME (HOURS) 800 900 1000 1100 Transient Surge Current/Energy Transient 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. In the low power AC mains environment, industry TUBOEBSET6-*&$/&."BOE*&&& BMMTVHHFTUUIBUUIF worst case surge occurrence will be 3kA. Such a transient event may occur up to five times over the equipment life time (approximately 10 years). While the occurences of five 3kA transients is the required capability, the rated, repetitive surge current for the C-III Series is 80 pulses for the 20mm units and 40 pulses for the 14mm Series. 500 V130LA20C 3kA (8/20μs) 450 400 350 (RATED FOR 80 PULSES) 300 0 10 20 30 Figure 13 CLAMPING VOLTAGE AT 750A As a measure of the inherent device capability, samples PGUIFNN7-"$EFWJDFTXFSFTVCKFDUFEUPB worst case repetitive transient surges test.
