TPC 1 Zinc Oxide Varistors General Metal Oxide Varistors are ceramic passive components made of zinc oxide sintered together with other metal oxide additives. They provide an excellent protective device for limiting surge voltages and absorbing energy pulses. Their very good price / performance ratio enables designers to optimize the transient protection function when designing the circuits. Varistors are Voltage Dependent Resistors whose resistance decreases drastically when voltage is increased. When connected in parallel with the equipment to protect, they divert the transients and avoid any further overvoltage on the equipment. Manufactured according to high level standards of quality and service, our Metal Oxide Varistors are widely used as protective devices in the telecommunications, industrial, automotive and consumer markets. 2 TPC Zinc Oxide Varistors Introduction or, yet again, by changing the chemical composition of the varistor. The polycrystal is schematically represented in Figure 3. At room temperature the semiconducting grains have very low resistivity (a fews ohms/cm). ZINC OXIDE VARISTORS. PROTECTION FUNCTION APPLICATION Definition of the varistor effect The varistor effect is defined as being the property of any material whose electrical resistance changes non-linearly with the voltage applied to its terminals. In other words, within a given current range, the current-voltage relationship can be expressed by the equation: I = KV a In which K represents a constant depending on the geometry of the part and the technology used and a the non-linearity factor. The higher the value of this factor, the greater the effect. The ideal (and theorical) case is shown in Figure1 where a = whereas a linear material has an equation of I = f(V) obeying the well-known Ohm's law (a = 1). The relationship between these two extreme cases is shown in Figure 2. It should be pointed out that the I = f(V) curve is symmetrical with respect to zero in the case of zinc oxide varistors. Current a= a Current Intergranular phase Zinc oxide grains Figure 3 On the contrary, the resistivity of the second phase (or intergranular layer) basically depends on the value of the applied voltage. If the voltage value is low, the phase is insulating (region I of the I = f(V) curve). As the voltage increases this phase becomes conductive (region II). At very high current values the resistivity of the grain can become preponderant and the I = f(V) curve tends towards a linear law (region III). The curve I = f(V) for the different types can be found in corresponding data sheets. 2 - Equivalent electrical circuit diagram =1 0 0 Voltage Voltage Figure 1 Figure 2 ZINC OXIDE VARISTORS 1-Composition of the material Zinc oxide varistors are a polycrystalline structured material consisting of semiconducting zinc oxide crystals and a second phase located at the boundaries of the crystals. This second phase consists of a certain number of metallic oxides (Bi2O3,MnO,Sb2O3, etc.). It forms the heartof the varistor effect since its electrical resistivity is a non-linear function of the applied voltage. Thus, a zinc oxide varistor consists of a large number of boundaries (several millions) forming a series-parallel network of resistors and capacitors, appearing somewhat like a multijunction semiconductor. Experimentally, it is found that the voltage drop (at 1mA) at each boundary is about 3V. The total voltage drop for the thickness of the material is proportional to the number N of boundaries. t V1mA o3 N where N = -- L in which L represents the average dimension of a zinc oxide grain and t the thickness of the material. t In other words: V1mA o3 -- L Thus, with a thickness of 1 mm and average dimension of L = 20 , we obtain a voltage of 150 V for a current of 1mA. The desired voltage at 1mA can thus be obtained either by changing the thickness of the disc or by controlling the average dimension of the zinc oxide grain through heat treatment Figure 4 explains the behavior of a zinc oxide varistor. r represents the equivalent resistance of all semiconducting grains and r that of the intergranular layer (the value of which basically varies with the applied voltage). Cp corresponds to the equivalent capacitance of the intergranular layers. When the applied voltage is low, the resistivity of the intergranular layer is quite high and the current passing through the ceramic is low. When the voltage increases, the resistance r decreases (region II in Figure 5). When a certain voltage value is reached, r becomes lower than r and the I = f(V) characteristic tends to become ohmic (region III). The equivalent capacitance due to the insulating layers depends on their chemical types and geometries. r { Zinc oxide grains III II Current I grains Cp boundaries { r>r r>r r>r Voltage = f (V) Figure 4 Figure 5 Values of a few hundred picofarads are usually found with commonly used discs. Capacitance value decreases with the area of the ceramic. Consequently, this value is lower when maximum permissible energy and current values in the varistor are low, since these latter parameters are related to the diameter of the disc. Capacitance values are not subject to outgoing inspection. TPC 3 Zinc Oxide Varistors Introduction 3 - Temperature influence on the I = f(V) characteristic The A versus curve A typical I = f(V) curve is given in Figure 6. Different distinct regions can be observed: * The first one depends on the temperature and corresponds to low applied voltages (corresponding currents are in the range of the A). Consequently, a higher leakage current is noticeable when temperature is increasing. * The second one shows less variation and corresponds to the nominal varistor voltage region (Figure 7). The temperature coefficient of the varistor voltage at 1 mA is: K= DV/V and has a negative value with K < 9.10-4/C DT As the temperature coefficient decreases with increasing current density, this curve also depends on the type of the varistor. * For higher voltages, the temperature has no significant influence. Practically the clamping voltages of the varistors are not affected by a temperature change. (I) V 1 mA A V 1 mA (%) A 0.5 0.1 a 1 10 20 Figure 8 4.2 - Non-linearity coefficient The peak current and voltage values basically depend on the I = f(V) characteristic or, to be more precise, on the value of the coefficient defined by: log (I1/I2) log (V1/V2) a= 10-4 +2 10-5 0 - 25 10-6 0 25 50 75 100 125 -2 10-7 10-8 100C 75C 10 102 -9.10-4 / C -4 25C (V) 10-9 103 Figure 6 In which I1 and I2 are the current values corresponding to voltage values V1 and V2. The value of a depends on the technology used (chemical composition, heat synthesis, etc.). Nevertheless, the value is not constant over the entire current range (several decades). For example, Figure 9 shows the variation of this coefficient for currents ranging from 100 nA to 100 A. It can be seen that a passes through a maximum value and always stays at high values, even at high levels of current. Figure 7 a 4 - Varistor characteristics The choice of a varistor for a specific application should be guided by the following major characteristics: 1) Working or operating voltage (alternating or direct). 2) Leakage current at the working voltage. 3) Max. clamping voltage for a given current. 4) Maximum current passing through the varistor. 5) Energy of the pulse to be dissipated in the varistor. 6) Average power to be dissipated. l1/ l2 a = Log Log V / V 1 2 where l1 = 10 l2 60 50 b= 40 30 (I) A 4.1 - Max. operating voltage and leakage current The maximum operating voltage corresponds to the "rest" state of the varistor. This "rest" voltage offers a low leakage current in order to limit the power consumption of the protective device and not to disturb the circuit to be protected. The leakage currents usually have values in the range of a few micro-amperes. PA = AV .lp = AKVpa+1 with PA = A PC a in which: A = a constant f( ) K = a constant (I = KVa). PC = dissipated power for a DC voltage Vp. 100 For usual values of (30 to 40), the continuously dissipated power is about 7 times greater than that dissipated by a sinusoidal signal having the same peak value. For example, a protective varistor operating at RMS voltage of 250 V has a power dissipation of a few mW. 10-3 4 50 10-6 10-3 10 102 1.9 1.8 1.7 1.6 1.5 1.4 1.3 1.2 1.1 V1 V2 V 2 = Voltage for l2 l1 > l2 l1 = 106 l2 l1 3 l2 = 10 10 Figure 9 V 1 = Voltage for l1 20 30 a Figure 10 The non-lineary of the varistor can be expressed in another way by the ratio of the voltages corresponding to 2 current values. = V1 V2 b Where: V1 voltage for current I1 V2 voltage for current I2 The curve giving versus the value of a is shown in Figure10 for 2 ratios of I1 /I2 =103 and 106. b TPC Zinc Oxide Varistors Introduction 4.3 - Clamping voltage It is the maximum residual voltage Vp across the varistor terminals for a through current Ip. The voltage value gives an indication on the protective function of the varistor. 4.4 - Permissible peak current The value of the permissible peak current depends upon the varistor model and waveform (8 x 20 s, 10 x 1000 s, etc.). It can be seen that, as a first approximation, the permissible peak current is proportional to the area of the varistor electrodes. By way of example, Table I gives the permissible peak current values for different diameters and for one current surge of waveform 8 x 20 s. It corresponds to a maximum permissible variation of 10% in the voltage measured at 1 mA dc after the surges. Overloads greater than specified values may result in a change in varistor voltage by more than 10% and irreversible change in the electrical properties. In case of heavy overload, surge currents beyond the specified ratings will puncture the varistor element. In extreme cases, the varistor will burst. Opposite, we have expressed energy W calculated for different pulse shapes, assuming that the value of the coefficient equals 30. a a) Voltage surge Figure 11 - 12 - 13 - 14 b) Current surge Figure 15 - 16 - 17 - 18 If, for example, we take a current surge as shown in Figure 19, we demonstrate that the dissipated energy is given by the approximate expression: W = Vp Ip (1.4 2 - 0.88 1 ) 10-6 in which Vp is the peak voltage value and Ip the peak current value. W is expressed in joules. in seconds. Vp in volts. Ip in amperes. t t V Operating Voltage (V) 250 250 250 250 250 Uncoated Disc [ (mm) 5 7 10 14 20 Number of Current Surges (8 x 20 s) 1 2 102 104 Ic = KVc V = Vc _t t V I = KV -2 W = 310 Ic Vc Vc Vc Table I t t 0 0 Figure 11 V Permissible Current (A) 6500 4000 1000 200 V = Vc W = Ic Vc t I max.

Indeed, except in special cases, the overvoltages occur at random and not at a high repetition frequency. Therefore, aging of the varistor will be related to energy of the transient defined by the current and peak voltage values as well as the pulse shape. -t 1.4 t Vc 0 The permissible peak current also depends on the number of current surges applied to the varistor. For example, Table II gives the permissible current values based on the number of consecutive surges of the same magnitude applied on varistor model VE24M00251K. Thus, the smaller the number of surges, the higher the permissible current.

Current Ip Ip/2 4.6 - Average dissipated power a) Average power dissipated in the "rest" state Considering the high values of the coefficient , a special a attention is required concerning the dissipated power value in case of possible changes in the operating voltage. Indeed, starting with the equation: I = KVa the average power dissipated by the varistor is given by the equation: PC = KV +1 when a direct current voltage is applied, and PA = APC in the case of a sinusoidal voltage having the same peak value and direct current voltage value. a 0 t1 t 2 Time Figure 19 P/P0 105 Table III Vp (V) Ip (A) Waveform (s) Energy (J) 104 500 300 1.2 50 10 500 300 103 8 20 3 500 300 10 1000 210 1 Uncoated Disc o (mm) 5 7 10 14 20 Energy (J) 10 21 40 72 130 10 1 1.1 1.2 1.3 V/V 0 Figure 20 The A value as a function of a was given in Figure 8. A small change of the operating voltage can induce a dissipated power variation which is all the more greater since the value of exponent a is high (Figure 20). the dissipated power by a factor of 20 when coefficient a equals 30, and by a factor of 150 when the coefficient equals 50. Table V gives the power P dissipated at values of the applied direct current voltage when the value of a equals 30. b) Average power dissipated during the transient state If the transients to which the varistor is subjected are repeated at a sufficiently high frequency, there will be an increase T in the average temperature of the part given by the expression: T = P/ in which P represents the average dissipated power which depends on the energy of the pulse and its repetition frequency and d the dissipation factor in air of the unit. This temperature rise should stay below the threshold indicated by the manufacturer or it may damage the component coating resin or even cause thermal runaway of the ceramic. d Table V 6 a = 10 102 It can be seen that a 10% change in the rated voltage increases Table IV V- (V) 180 220 230 a = 30 2 The following changes are found when the varistor absorbs an energy greater than the maximum permissible value: * Higher leakage current. * Decrease in the voltage at 1 mA. * Decrease in coefficient . a If the energy increases well beyond the maximum value, the characteristics degrade to such an extent that, even at the rated voltage, the varistor has a very low resistance value. The permissible energy for a given varistor is mainly related to the size of the part. For example, Table IV gives the permissible energy for different varistors sizes with an operating voltage of 250 V.

The nominal voltage of a varistor (or "varistor" voltage) is defined as the voltage drop across the varistor when a dc test current of 1 mA is applied to the component. It is defined at a temperature of 25C. This parameter is used as a standard to define the varistors but has no particular electrical or physical significance. 5.2 - Practical response time However, the response time will be modified for several reasons: * Parasitic capacitance of the component due to the insulation of the intergranular layers. * Overshoot phenomenon occurring when the varistor is subjected to a voltage with a steep leading edge (Figure 21) and causing a dynamic voltage peak greater than the static voltage by a few percent. * Impedance of the external circuit to the varistor. In conclusion, the practical response time of a zinc oxide varistor usually stays below 50 nanoseconds. Volts Generator at 50 100 80 Generator at 50 + zinc oxide varistor 60 6.2 - Tolerance on the varistor voltage The standard tolerance is 10%. Other tolerances may be defined on custom design products. To avoid any lack of understanding, different behaviors of Zn0 varistors should be noted when considering the measurement of V 1 mA. * The measurement time must not be too short to allow a "break-in" stabilization of the varistor and not too long so the measurement is not affected by warming the varistor. The limits of V1mA for our products are given for a measurement time comprised between 100 ms and 300 ms. For times comprised between 30 ms and 1s, the varistor voltage will differ typically by less than 2%. * The value of the peak varistor voltage measured with ac current will be slightly higher than the dc value. * When the varistor has been submitted to unipolar stresses (pulses, dc life test, ...) the voltage-current characteristic becomes asymmetrical in polarity. 40 20 0 20 40 60 80 Nanoseconds Figure 21 TPC 7 Zinc Oxide Varistors Applications 1 - Principle of application Zinc oxide varistors are essentially used as protective devices for components or items of equipment subjected to electrical interference whether accidental or otherwise. To be more specific, there are two types of interference: those which can be controlled (switching of resistive or capacitive circuits) and those which occur at random (high voltage surges change in the power supply network, etc.) The "protection" function is related to the non-linear I = f(V) characteristic of the varistor. This component is always connected in parallel with the assembly E to be protected (Figure 22B). The varistor's "rest" state has a very high impedance (several megohms) in relation to the component to be protected and does not change the characteristics or the electric circuit. In the presence of a transient, the varistor then has a very low impedance (a few ohms) and short circuits the component E. The "rest" and operating states are shown in Figure 22A and 22B. In case of a current surge of a peak value Ip, the higher the non-linear coefficient a is, the lower the voltage across the terminals of the component E will be: Vp = (Ip/K) 1/ a In case of a voltage surge Vs, the varistor limits the voltage across the terminals of component E to a value Vp via resistor Rc which can be the impedance of the source (Figure 23). E Id-cor a-c "Rest" state Figure 22A E Ip Protective state Figure 22B Vs Rc Vp E 2 - Main applications Varistors are widely used in the different electronic equipment: * telecommunication and data systems power supply units, switching equipment, answering sets, ... * industrial equipment control and alarm systems, proximity switches, transformers, motors, traffic lighting, ... * consumer electronics television and video sets, washing machines, electronic ballasts, ... * automotive all motor and electronic systems. 8 TPC Figure 23 Zinc Oxide Varistors Applications Three typical examples of applications are shown to illustrate the "protection" function of zinc oxide varistors. 1 - Protection of relay contacts It is a well-known fact that a sudden break in an inductive circuit causes an overvoltage which can seriously damage the contacts of relay due to arcing. Overvoltages of several thousand volts can occur across the terminals of unprotected relay contacts. This disadvantage can be overcome by limiting the overvoltage due to opening an inductive circuit to a level such that it cannot generate an arc. Such limitation is achieved by wiring a zinc oxide varistor in parallel across the terminals of the relay characterized by the value of its inductance coil L and its resistor R (Figure 24). L R Figure 24 2 - Protection of a diode rectifier bridge Semiconductor components (silicon diodes, thyristors, etc.) are especially sensitive to transients and must be protected so that the overvoltage value is limited to levels which are not dangerous. An example of protection for a diode rectifier is schematically represented in Figure 25. The varistor is connected to the transformer secondary at the input of rectifier bridge. If the transformer's magnetizing current is interrupted when it reaches its maximum value, a voltage ten times greater than the normal value can then appear at the terminals of the secondary winding in the absence of a load. Figure 25 This overvoltage, which is excessive for the semiconductors, is limited by the presence of the varistor which absorbs the energy corresponding to the change of state of the primary circuit. The same varistor can also protect the rectifier bridge against overvoltages coming from the mains and reaching the secondary circuit via the stray capacitance of the transformer. Another practical case to be considered involves closing of the primary circuit. If the circuit is closed when the primary voltage reaches its maximum value, the secondary voltage can be two times greater than its steady-state value. Although this case is less dangerous than the preceding one, it still may cause damage to the rectifying diodes. Connection of a varistor in parallel limits this overvoltage to a value such that it does not cause any damage to the semiconductors. 3 - Opening of a resistive circuit supplied with AC current with a loadless rectifier The diagram is given in Figure 26. When the circuit supplied with AC current is opened, an overvoltage appears across the rectifier terminals: - Ldi/dt The energy stored by the inductance coil (1/2 L I2 rms) is transferred to the protective varistor wired in parallel to the inductance coil.

All products are tested and released by the quality department based on the compliance to established customer specifications. Critical raw materials are inspected for dimensional, electrical and physical properties prior to releasing to the production floor. Routine checks are carried out at crucial processes. The finished products are submitted to Quality Control for inspection on electrical, dimensional, physical & visual conformance to relevant specifications, based on established AQLs. The average outgoing quality level is < 10ppm on TPC varistors. The low ppm value is applicable for total functional failures, i.e. short circuit and open circuit. TPC varistors are subjected to reliability tests stated in page 37 (per CECC 42000). Life test is conducted to determine the life time of varistors. The test conditions used are stated in page 00. The varistors are subjected to these conditions for a minimum period of 1000 hours. Failure in time (FIT) is computed for all tested parts based on Arrhenius equation. The definition of failure is a shift in the nominal voltage exceeding 10%. The FIT calculation is computed in units of 10-9/h. Figures below give the FIT for low and high voltage varistors. The FIT values at various stresses are extrapolated based on Arrhenius equation.
