4 FEATURES Page 4 * Wide operating voltages ranging from 5Vrms to 1000Vrms (6Vdc to 1465Vdc). * Fast response time of less than 25nS, instantly clamping the transient over voltage. * High surge current handling capability. * High energy absorption capability. * Low clamping voltages, providing better surge protection * Low capacitance values, providing digital switching circuitry protection. * High insulation resistance, preventing electric arching to the adjacent devices or circuits. APPLICATIONS * Transistor, Diode, IC, Thyristor or Triac semiconductor protection. * Surge protection in consumer electronics. * Surge protection in industrial electronics. * Surge protection in electronic home appliances, gas and petroleum appliances. * Relay and electromagnetic valve surge absorption. The Prevention of Overvoltge * Rest State : Varistor with high resistance allows only very small electrical current passing through. The current is so called leakage current. * Protective State : When surge current happened, the resistance of varistor suddenly dropped to few ohm. With such low resistance, it allows the surge current passing through and further protects other devices that parallel with Varistor. It is so called breakdown phenomena.

Normal Varistor Region of Operation The varistor is in a high resistance mode (approaching 10^9 Ohm) and appears as an open circuit. Upturn Region of Operation The varistor characteristic follows the equation I=KVα. At high current, approaching the maximum rating, the varistor approximates a short-circuit.

6 Page 6 HOW TO SELECT A MOV (Metal Oxide Varistor) Three steps for most of applications, 1) Allowable : (What is the operation / working?) 1.1 What type of the power source? AC or DC? 1.2 Be careful with the Stability of Power Soruce: ±10%, ±20% or ±30%? 1.3 From Song Long Catalog, select the Allowable (1mA or 0.1mA ) that equal or higher than the power source peak working voltage 1.4 After the selection, it will also refer to the Varistor (Vb). A simple calculation: Vac = x 0.63 ; Vdc = Vb@1mA x ) Clamping : (What is acceptable transient to the equipment?) 2.1 Under a certain current, what is the maximum transient voltage that the equipment or the device to be protected can withstand? 2.2 From 1.3 selection, choose a Clamping that the equipment can endure. It is easy to find a MOV clamping voltage from V-I curve when the transient current is know. 2.3 It may refer to a minimum MOV size, or special design MOV with specify clamping voltage. 3) The MOV Size (Diameter): (The concerns of using MOV safely.) Find the suitable MOV in diameter that can meet the following requirements 3.1 Withstanding Transient (10/1000μs) To determine the energy absorbed by the MOV, the following equation can apply: =K * Vclamp(V) * Ipeak(A) *Time(S) Where K is a constant. K value is 1.0 for a rectangular waveform, 1.4 for a 8/20µS and 10/1000μS waveform. And Ip is the peak current applied, Vc is the clamping voltage which was current applied. T is the pulse width. Current (%) t = Time from 10% to 90% of peak t1 = Virtual front time =1.25 * t t2 = Virtual time to Half value (Impulse Duration) Example : For 8/20 μ S Current Waveform: 8 μ S = t1 20 μ S = t2 For 10/1000 μ S Current Waveform: 10 μ S = t μ S = t2 t1 & t2 Tolerance ± 20% 10 t t1 t2 Time ( μ S) The issued energy does not represent the quality of MOV, but can be a valuable indication when comparing the different series of MOV which have the same varistor voltage. A MOV with better (less) clamping voltage will absorb less energy, but with better performance to protected device. Withstanding Surge Current (8/20μs) The maximum peak current that can be applied to the varistor for a single 8/20μS current waveform, with line voltage applied, without causing device failure. The Surge Life Time Rating The number of expected transients in the circuit and the impulse current decide the life of MOV. From the circumstance to select the suitable model MOV that can endure the life time impacts.

7 NOTICE FOR APPLICATION Page 7 Please refer and apply following notice to prevent the troubles and degradation of MOV The troubles of a MOV may cause fire and / or degradation of your appliances. 1) In case the huge surge and / or excess voltage applied, MOV may be broken, heated, smoked, arced, fired and exploded. To prevent such situation, fuse or circuit braker can be set in series with MOV or in between the power source side and MOV. Recommended fuse ratings Diameter 05D 07D 10D 14D 20D Fuse rated current 1~2A 2~3A 3~5A 3~10A 5~15A 2) Don't apply in excess of the limit of energy and surge. 3) In case of grounding troubles on 100V single phase 3 line power source, 200V is possibly applied across the line and ground. If you apply the varistors for the higher voltage like the lightening surge, you are suggested to apply the varistor for 220V power line. 4) Varistor has the capacitive impedance to cause a heating and / or troubles in case of high frequency application. 6) Such a high temperature ambient like a direct sun exposure or the vicinity of heating element may cause an excess temperature for varistor performance. 7) Watery or high humidity area, corrosive, salty or dusty ambient be avoided. 8) Storage condition: be -10 ~ +40, 75%R.H. or below, without rapid temperature change to varistor. 9) Alcoholic base solvent is suggested for flux cleaning, acetone, thinner or strong solvent be avoided. 10) To apply resin coating, please inquire about the selection of resin. Some resin may affect to the varistor performance, be sure to confirm the varistor performance after resin coating. 11) Mechanical force like shock or pressure to damage visually, be avoided. 12) Flammable materials should not be positioned in the vicinity of varistor. 13) For lead trimming, body side of leads should be clamped. 14) For soldering, conditions be selected so as the solder of varistor and coating resin are not be melted or softened.

8 Page 8 15) Determine power dissipation requirements. If the transients generate heat too quick, the heat transfer will not complete during the pulse interval. It will cause MOV malfunction. The MOV can only dissipate a relatively small amount of heat (energy) and therefore are not suitable for repetitive applications that involve substantial amounts average energy dissipation. Furthermore, the operating values will be decreased at high temperatures as shown in following figure. PERCENT OF RATED VALUE AMBIENT TEMPERATURE( )

9 Page 9 About MOV MOV - Metal Oxide Varistor --a component used to suppress voltage transients. MOV is what's inside a lot of small "surge supressors" in a sturcture having a multi-grain ceramic semiconductor. It has a rather high resistance until the voltage gets over a threshold, at which time the resistance drops (but not to zero).
