SCHOTTKY RECTIFIER  
10 Amp  
TO-262  
Major Ratings and Characteristics  
Description/Features  
The 10CTQ150L center tap Schottky rectifier has been opti-  
mized for low reverse leakage at high temperature. The  
proprietarybarriertechnologyallowsforreliableoperationupto  
175° C junction temperature. Typical applications are in  
switching power supplies, converters, free-wheeling diodes,  
and reverse battery protection.
