Power Dissipation Ratings

power dissipation is the energy (watt-seconds) per pulse
times the number of pulses per second. The power so
developed must be within the specifications shown on the
%FWJDF3BUJOHTBOE4QFDJmDBUJPOT5BCMFGPSUIFTQFDJmD
device. The operating values of a MOV need to be derated
at high temperatures as shown above. Because varistors
only dissipate a relatively small amount of average power
they are not suitable for repetitive applications that involve
substantial amounts of average power dissipation.
