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.

Revision: September 9, 2010 C-III Varistor Series C–III Series Varistor Products Radial Lead Varistors > C-III series Power Dissipation Ratings Peak Pulse Current Test Waveform PERCENT OF PEAK VALUE 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. 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. 100 90 50 10 O1 T T1 T2 TIME Current Energy and Power Derating Curve Figure 2 100 01 = Virtual Origin of Wave T1 = Rise Time = 1.25 x T T2 Example μ μs = T1 = Rise Time 20μs = T2 PERCENT OF RATED VALUE 90 80 70 60 50 40 30 20 10 0 -55 50 60 70 80 90 100 110 120 AMBIENT TEMPERATURE ( oC) 130 140 150 Figure 1 Transient V-I Characteristics Curves Maximum Clamping Voltage for 10mm Parts V130LA5C(P) – V460LA10C(P) 10,000 Pulse Rating Curves Repetitive Surge Capability for 10mm Parts V130LA5C(P)-V320LA10C(P) 10,000 MODEL SIZE = 10mm 1 V460LA10C(P) V320LA10C(P) RATED PEAK SURGE CURRENT (A) 2 1,000 10 10 2 10 3 100 MODEL SIZE = 10mm TA = -55oC TO 85 oC 130 TO 625VM(AC) RATING 104 105 106 Maximum Voltage (V) V300LA10C(P) V275LA10C(P) V250LA10C(P) 1,000 V230LA10C(P) ∞ 10 V175LA5C(P) V150LA5C(P) V140LA5C(P) V130LA5C(P) 100 0.001 0.01 0.1 1 10 Peak Amperes (A) 100 1000 10000 1 10 100 1,000 10,000 Figure 3 Figure 4 SURGE IMPULSE DURATION (μs) C-III Varistor Series Revision: September 9, 2010 ©2010 Littelfuse, Inc.

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 this type of varistor is still functioning normally after this tolerance will begin to dissipate more power. 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.

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. Typical Repetitive Surge Current Capability of C-III Series MOVs CLAMPING VOLTAGE AT 3kA 500 V130LA20C 3kA (8/20μs) 450 400 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 repetitive surge current for the C-III Series is 20 pulses for the 20mm units and 10 pulses for the 14mm Series. 350 (RATED FOR 20 PULSES) 300 0 5 10 15 20 NUMBER OF SURGES 25 30 Figure 13 CLAMPING VOLTAGE AT 750A 600 550 500 450 400 350 300 0 (RATED FOR 120 PULSES) 50 100 150 200 NUMBER OF SURGES a worst case repetitive transient surges test.
