Description
LA series transient surge suppressors are radial-lead varis-
tors that can be operated continuously across AC power
lines. These UL recognized varistors “across-the-line” com-
ponents, because of their radial lead construction, require
very little mounting space. This feature is particularly impor-
tant in compact, hard wired system designs.
LA series varistors are available in four model sizes: 7mm,
10mm, 14mm and 20mm; and have a VM(AC)RMS voltage
range from 130V to 1000V, and an energy absorption
capability up to 360J. Some LA series model numbers are
available with two clamping voltage selections, designated
by a model number prefix of either A or B. The “A” selection
is the standard model; the “B” selection provides a tighter
clamping voltage.

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 Specifications 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.
