Advantages of various types of varistors
Varistors can be used as suppressors to protect devices and circuits from transient abnormal voltages including an ESD (electrostatic discharge) and a lightning surge.
For protection from a relatively large surge current (100A to 25kA), leaded disk varistors and SMD disk varistors are suitable. For protection from a larger surge current (approximately 25kA or more), block varistors, and strap varistors are suitable.
For industrial devices and energy apparatuses, disk varistors of which maximum allowable circuit voltage (rated voltage) and maximum peak current are large are used.
● Leaded disk varistors
● ThermoFuse varistors
● SMD disk varistors
● Strap varistors
● Block varistors
