LA Varistor Series
The LA Series of transient voltage surge suppressors are radial-lead
varistors (MOVs) that are designed to be operated continuously across
AC power lines. These UL recognized varistors require very little
mounting space, and are offered in various standard lead form options.
The LA Series varistors are available in four model sizes: 7mm, 10mm,
14mm and 20mm; and have a V
voltage range from 130V
M(AC)RMS
to 1000V, and an energy absorption capability up to 360J. Some LA
series model numbers are available with clamping voltage selections,
designated by a model number suffix of either A or B. The “A” selection is
the standard model; the “B” selection provides a lower clamping voltage.
See LA Series Device Ratings and Specifications table for part number
and brand information.

NOTE: Average power dissipation of transients not to exceed 0.25W, 0.4W, 0.6W or 1W for model sizes 7mm, 10mm, 14mm and 20mm, respectively.
Power Dissipation Ratings
Should transients occur in rapid succession, the average power dissipation
100
90
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 Figure 1. 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.

NOTE: If pulse ratings are exceeded, a shift of V
N(DC)
(at specified current) of more than 10% could result. This type of shift, which normally results in a decrease of V ,
N(DC)
may result in the device not meeting the original published specifications, but does not prevent the device from continuing to function, and to provide ample protection.
