Vishay High Power Products
FEATURES
• Ultrafast recovery time
• Low forward voltage drop
• Low leakage current
• 175 °C operating junction temperature
• Compliant to RoHS directive 2002/95/EC
• Designed and qualified for industrial level
DESCRIPTION/APPLICATIONS
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.
