RHRU7570, RHRU7580, RHRU7590, RHRU75100
Data Sheet April 1995 File Number 3925.1
75A, 700V - 1000V Hyperfast Diodes
RHRU7570, RHRU7580, RHRU7590 and RHRU75100
(TA49068) are hyperfast diodes with soft recovery characteristics (t
< 85ns). 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.
