Description
CH series transient surge suppressors are small, very com-
pact metal-oxide varistors. They are intended for use in
hybrid circuit applications in commercial and industrial
equipment utilizing direct surface-mounting techniques.
These devices, which have significantly lower profiles than
traditional radial-lead varistors, permit designers to reduce
the size and weight and increase the reliability of their equip-
ment designs.
CH series varistors are available in a voltage range from
10V to 275V VM(AC)RMS, and energy ratings up to 23J.

Power Dissipation Ratings
Continuous power dissipation capability is not an applicable
design requirement for a suppressor, unless transients occur
in rapid succession. Under this condition, 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 specifications shown on the
Device Ratings and Characteristics table for the specific
device. Furthermore, the operating values need to be der-
ated 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.
