150A, 900V - 1000V Hyperfast Diodes
RHRU15090 and RHRU150100 (TA49072) are hyperfast
diodes with soft recovery characteristics (t
RR
< 90ns). 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 rectifiers 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.
