MA Varistor Series
Description
The MA Series of transient surge suppressors are axial
lead Metal Oxide Varistors (MOVs) for use in a wide
variety of board level industrial and commercial electronic
equipment. They are intended to protect components and
signal/data lines from low energy transients where the
small axial lead package is required.
The MA Series is offered with standard ('S' suffix) or
tightened ('B' suffix) clamping voltage.
See MA Series Device Ratings and SpecificationsTable for
part number and brand information.

T =Time from 10% to 90% of Peak
T1 = RiseTime = 1.25 xT
T2 = DecayTime
Example - For an 8/20 µs Current Waveform:
8µs =T1 = RiseTime
Should transients occur in rapid succession, 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 derated at high
temperatures as shown above. 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.

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 it does not
prevent the device from continuing to function, and to provide ample protection.
