Description
RURD610CC, RURD615CC, RURD620CC, RURD610CCS,
RURD615CCS and RURD620CCS are ultrafast dual diodes
with soft recovery characteristics (t
RR
< 25ns). They have low
forward voltage drop and are silicon nitride passivated ion-
implanted epitaxial planar construction.
These devices are intended for use as freewheeling/clamping
diodes and rectifiers in a variety of switching power supplies
and other power switching applications. Their low stored charge
and ultrafast soft recovery minimize ringing and electrical noise
in many power switching circuits reducing power loss in the
switching transistors.
