AK3-Y Series  
Description  
The AK3-Y series of high powerTVS diode is specially  
designed for meeting severe surge test environment of  
both AC and DC line protection applications. It features a  
very fast response and ultra low clamping characteristics  
as compared to MOVs (Metal Oxide Varistors). It  
accomplishes this by virtue of the Littelfuse FoldbackTM  
technology,which provides a clamping voltage lower  
than the avalanche voltage (but above the rated working  
voltage); therefore, any voltage rise due to increased  
current conduction is maintained at a minimum magnitude,  
providing the best possible protection level. These AK  
components can be connected in series and / or parallel to  
create a very high surge current protection solution.
