LA Varistor Series
Description
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 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 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.

Power Dissipation Ratings
Peak Pulse CurrentTestWaveform
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.The operating values of a MOV need to be derated
at high temperatures as shown above. 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 VN(DC) (at specified current) of more than 10% could result. This type of shift, which normally results in a decrease of VN(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.
