NOTE:
1. Average power dissipation of transients should not exceed 0.25W, 0.4W, 0.6W and 1.0W for 7mm, 10mm, 14mm, and 20mm model sizes, respectively.
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. Furthermore, the operating values
need to be derated at high temperatures as shown in
above. Because varistors can only dissipate a relatively
small amount of average power they are, therefore,
not suitable for repetitive applications that involve
substantial amounts of average power dissipation.
