DURB2020CT  
Description  
Littelfuse DUR series Ultrafast Recovery Rectifier is  
designed to meet the general requirements of commercial  
applications by providing lowTrr, high-temperature, low-  
leakage and low forward voltage drop products. It is suit-  
able for output rectifier, free-wheeling or boost diode in  
high-frequency power switching application such as switch  
mode power supply and DC-DC converters.  
Features  
• Ultra-fast switching  
mountTO-263 (D2PAK)  
package  
• Low reverse leakage  
current  
• Pb-free E3 means 2nd  
level interconnect is  
Pb-free and the terminal  
finish material is tin(Sn)  
(IPC/JEDEC J-STD-  
609A.01)  
• High surge current  
capability  
• Low forward voltage drop  
• Common cathode  
configuration in surface
