75A, 400V - 600V Hyperfast Diodes
RHRU7540, RHRU7550 and RHRU7560 (TA49067) are
hyperfast diodes with soft recovery characteristics
(t
RR
< 55ns). They have half the recovery time of ultrafast
diodes and are silicon nitride passivated ion-implanted epi-
taxial 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.
