| ---Product Description--- |
Metal Oxide Varistor (MOV) is also known as Varistors that stands for variable resistors. It is a voltage-dependent resistor (also
known as VDR) with bidirectional and symmetrical V/I characteristics (Fig.1).
Varistor is polycrystalline ceramic devices exhibiting highly nonlinear electrical behavior and greater energy absorption
capability. The fabrication of varistor is done by mixing semiconducting ZnO powder with other oxide powders, and subjecting
the powder mixture to conventional ceramic pressing and sintering. The sintering results in a polycrystalline ceramic with
grain-boundary property which produces the nonlinear current-voltage characteristics of the device (Fig. 2).

| Advantages Compared with Other Transient Suppressors:
1. Better Thermal Properties
A silicon suppressor has only one P-N junction to handle the current, but varistor has millions of P-N junctions to offer better
energy dissipation capability and peak current handling capability.
2. Speed of Response
The action of varistor is similar to that of other semiconductor devices, and its conduction happens very fast (nanosecond
range). In other words, varistor is fast enough to response to any practical requirements.
3. Stable Clamping Voltage over Temperature
Beyond the breakdown point, the clamping voltage of varistor is almost constant over wide range of operating temperature
while the clamping voltage of zener diode is higher at upper operation temperature. Even though leakage current of varistor
increases following the rise of temperature, its clamping voltage is temperature independent.
4. Capacitance
Compared with zener diodes, varistors have higher capacitance. Depending on the application, transient suppressor
capacitance can be a desirable or undesirable feature. In DC circuits, the capacitance of varistors provides both decoupling
and transient voltage clamping functions.
5. Less Expensive
Compared with diodes, varistor has small size and is cost-effective. Specifications
