RHRP840, RHRP860
Data Sheet January 2002
8A, 400V - 600V Hyperfast Diodes
The RHRP840 and RHRP860 are hyperfast diodes with soft
recovery characteristics (t
< 30ns). They have half the
rr
recovery time of ultrafast diodes and are silicon nitride
passivated ion-implanted 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.
Formerly developmental type TA49059.
