Description
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 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.
These devices are supplied in the single lead JEDEC style
TO-218 plastic package.
Due to space limitations, the brand on the RHRU75100 is
abbreviated to HRU75100.
To order this part use the full part number, i.e. RHRU75100.
