Ultrafast Rectifier
Bulletin PD-20737 rev. C 12/03
MURD620CT
Features
• Ultrafast Recovery Time
• Low Forward Voltage Drop
• Low Leakage Current
• 175°C Operating Junction Temperature
Description/ Applications
International Rectifier's MUR.. series are the state of the art Ultra
fast recovery rectifiers specifically designed with optimized
performance of forward voltage drop and ultra fast recovery time.
The planar structure and the platinum doped life time control,
guarantee the best overall performance, ruggedness and reliability
characteristics.
These devices are intended for use in the output rectification
stage of SMPS, UPS, DC-DC converters as well as free-wheeling
diode in low voltage inverters and chopper motor drives.
Their extremely optimized stored charge and low recovery
current minimize the switching losses and reduce over dissipation
in the switching element and snubbers.
