1. Average power dissipation of transients not to exceed 0.2W, 0.25W, 0.4W, 0.6W or 1W for model sizes 5mm, 7mm, 10mm, 14mm and 20mm,  
respectively.  
2. Energy rating for impulse duration of 30ms minimum to one half of peak current (auto load dump).  
3. 10mA DC test current.  
4. Also rated to withstand 24V for 5 minutes.  
5. Higher voltages available, contact Littelfuse.  
Also listed to UL1449, Second Edition, “Transient Voltage Surge Suppressors” File #E75961.

1.  
Power Dissipation Ratings  
Should transients occur in rapid succession, the average  
power dissipation required is simply the energy (watt-  
100  
90  
80  
70  
60  
50  
40  
30  
20  
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 in Figure 1.  
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 ofV (at specified current) of more than 10% could result.This type of shift, which normally results  
N(DC)  
, may result in the device not meeting the original published specifications, but it does not prevent the device from continuing  
in a decrease of V
