50A, 700V - 1000V Hyperfast Diodes
RHRU5070, RHRU5080, RHRU5090 and RHRU50100
(TA49066) are hyperfast diodes with soft recovery characteristics (t
< 75ns). They have half the recovery time of
RR
ultrafast diodes and are silicon nitride passivated ionimplanted 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.
