Ultrafast Recovery Rectifier
DURF2040CT, 2x 10A, 400V, ITO-220AB, Common Cathode
DURF2040CT
RoHS Pb e3
Description
Littelfuse DUR series Ultrafast Recovery Rectifier is
designed to meet the general requirements of commercial
applications by providing low Trr, 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
• Low reverse leakage
current
• High surge current
capability
• Low forward voltage drop
• Common Cathode
configuration in electrically
isolated ITO-220AB
package
• Pb-free E3 means 2nd
level interconnect is Pb-
free and the terminal finish
material is tin(Sn) (IPC/
JEDEC J-STD-609A.01)
