DescriptionIApplications
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.
trr = 25ns
|F(AV) = 8Amp
VR = 200V
The planarstructure 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.
