Ultrafast Recovery Rectifier
DURB2020CT, 2x 10A, 200V, TO-263, Common Cathode
DURB2020CT
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 surface
mount TO-263 (D2PAK)
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)
