1 High nergy, High Multiple Pulse Capability Radial Lead D V The C-III Series of metal-oxide varistors are specifically designed for applications requiring high surge energy absorption ratings and superior multiple pulse absorbtion 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. The C-III series is supplied in mm, mm and mm disc versions with various lead options. These types are shipped in bulk or Tape and Reel packaging. Part number and brand information is provided in the Ratings table. Features Lead-free and compliant option available. Please see the device and ratings specifications table for more information.

4 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 AMBINT TMPRATUR ( o C) Specifications table for the specific device.the operating values of a MOV need to be deratedat high temperatures as shown in Figure 1. Because varistors only dissipate a relatively small amount of average power they are not suitable 0for repetitive applications that involve substantial amounts of average power dissipation.,000 PRCNT OF RATD VALU FIGUR 1.

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 ±%. 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,000 device hours of operation at a temperature of 15 o C, although only rated at 85 o C. Changes in the nominal varistor voltage, measured at 1mA, of less than % have been recorded (Figure 8). Transient Surge Current/nergy 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 standards (UL, IC, NMA and I) 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 years). While the occu rences of five 3kA transients is the required capability, the rated, repetitive surge current for the C-III series is pulses for the mm units and pulses for the Additionally, all mm C-III devices are listed to the Permanently Connected category (ka) of UL49, by Underwriter s Laboratories, Inc. As a measure of the inherent device capability, samples of the mm V130LAC devices were subjected to a worst case repetitive transient surges test. After pulses, each of 3kA, there was negligible change in the device characteristics. Changes in the clamping voltage, measured at amps, of less than 3% were recorded (Figure 9). Samples of the mm Series V175LAC were subjected to repetitive surge occurrences of 7A. Again, there was negligible changes in any of the device characteristics after 00 pulses (Figure ). In both cases the inherent device capability is far in excess of the expected worst case scenario. V NOM AT 1mA (V) CLAMPING VOLTAG AT 3kA CLAMPING VOLTAG AT 7A 0 1 V130LAC TIM (HOURS) FIGUR 8.
