Vishay High Power Products

FEATURES

• Ultrafast recovery time

• Low forward voltage drop

• Low leakage current

• 175 °C operating junction temperature

• Lead (Pb)-free (“PbF” suffix)

• 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.
