Device Ratings and Specifications
Axial Lead
NOTE: Average power dissipation of transients not to exceed 200mW.
Power Dissipation Ratings
Should transients occur in rapid succession, the average power dissipation
required is simply the energy (watt-seconds) per pulse times the number
of pulses per second. The power so developed must be within the specifi-
cations 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 Figure 1. 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.
