MUR.. series are the state of the art ultrafast recovery
rectifiers specifically designed with optimized performance of
forward voltage drop and ultrafast 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-to-dc converters as well as
freewheeling 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.
