RURD660S9A_F085 Ultrafast Power Rectifier, 6A 600V
October 2013
RURD660S9A_F085
Ultrafast Power Rectifier, 6A 600V
Features
• High Speed Switching ( t
rr
=63ns(Typ.) @ I
F
=6A )
• Low Forward Voltage( V
F
=1.26V(Typ.) @ I
F
=6A )
• Avalanche Energy Rated
• AEC-Q101 Qualified
6A, 600V Ultrafast Rectifier
The RURD660S9A_F085 is an ultrafast diode with soft
recovery characteristics (trr< 83ns). It has a low forward
voltage drop and is of silicon nitride passivated ion-
implanted epitaxial planar construction. This device is
intended for use as a freewheeling/clamping diode and
rectifier in a variety of switching power supplies and
other power switching applications. Its low stored charge
and ultrafast soft recovery minimize ringing and electrical
noise in many power switching circuits, thus reducing
powerloss in the switching transistors.
Applications
• General Purpose
• Switching Mode Power Supply
• Power switching circuits
