Description
The RURP640CC, RURP650CC, and RURP660CC are
ultrafast dual diodes with soft recovery characteristics (t
RR
<
55ns). They have low forward voltage drop and are silicon
nitride passivated ion-implanted epitaxial planar construc-
tion.
These devices are intended for use as freewheeling/clamp-
ing diodes and rectifiers in a variety of switching power sup-
plies and other power switching applications. Their low
stored charge and ultrafast soft recovery minimize ringing
and electrical noise in many power switching circuits, reduc-
ing power loss in the switching transistors.
