Description:

Varistors provide reliable and economical protection against high voltage transients and surges which may be produced, for example, by lighting, switching or electrical noise on AC or DC power lines. They have the advantage over teansient suppressor diodes in as much as they can absorb much higher transient energies and can suppress positive and negative transients. When a transient occurs, the varistor resistance changes from a very high stand-by value to a very low conducting value . The transient is thus absorbed and clamped to a safe level, protecting sensitive circuit components Varistors are manufacturerd from a non-homogeneous material, giving a rectifying action at the contact points of two particals. Many series and parallel connections determine the voltage rating and the current capability of the varistor.
