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.

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.
