Metal-Oxide Varistors (MOVs)
Radial Lead Varistors > LA Varistor Series
Description
The LA Varistor Series of transient voltage surge
suppressors are radial leaded 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 Varistor Series 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.
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.
Phenolic Coating Option -- LA Series Varistors for Hi-Temperature Operating Conditions:
• Phenolic–coated LA Series devices are available with improved maximum operating maximum temperature 125°C.
• These devices also have improved temperature cycling performance capability.
• Ratings and Specifications are as per standard LA Series except Hi–Pot Encapsulation (Isolation Voltage Capability) = 500V.
• These devices are not UL, CSA, VDE or CECC certified.
• To order: add X1347 to end of part number (e.g. V230LA20APX1347).

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

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.
