Note:
Zinc Oxide Varistor is widely used in large filed of lightening protection,they are
specified according to the voltage range that they can tolerate without damage.
Other important parameters are the varistor's energy rating in joules, operating
voltage, response time, maximum current, and breakdown (clamping) voltage.
Energy rating is often defined using standardized transients such as 8/20
microseconds or 10/1000 microseconds, where 8 microseconds is the transient's
front time and 20 microseconds is the time to half value.
