4A, 400V - 600V Hyperfast Dual Diodes
The RHRD440CC, RHRD460CC, RHRD440CCS and
RHRD460CCS are hyperfast dual diodes with soft recovery
characteristics (t
rr
< 30ns). They have half the recovery time
of ultrafast diodes 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 hyperfast soft recovery minimize ringing
and electrical noise in many power switching circuits
reducing power loss in the switching transistors.
Formerly developmental type TA49055.
