LA Varistor Series
Power Dissipation Ratings
Should transients occur in rapid succession, the average
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
Device Ratings and Specifications Table for the specific
device.The operating values of a MOV need to be derated
at high temperatures as shown in the diagram below.
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.
