75A, 700V - 1000V Hyperfast Diodes
RHRU7570, RHRU7580, RHRU7590 and RHRU75100
(TA49068) are hyperfast diodes with soft recovery character-
istics (t
RR
< 85ns). 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/clamp-
ing diodes and recti鏗乪rs in a variety of switching power sup-
plies and other power switching applications. Their low
stored charge and hyperfast soft recovery minimize ringing
and electrical noise in many power switching circuits reduc-
ing power loss in the switching transistors.
