The Protection of semiconducting elements such as
diodes, thyristors, transistors, IC and relays against
transient Voltages.
Similar protection of many types of measuring
instruments, control machinery and communication
equipment and broadcasting equipment against
inductive lightning and switching surges.
Protection of general purpose electrical equipment,
domestic mechinery and appliances. TV and radios
and similar consumer products against lightning and
switching surges.
