6A, 1200V Ultrafast Diodes
The RURD6120 and RURD6120S are ultrafast diodes with
soft recovery characteristics (t
rr
< 70ns). They have low
forward voltage drop 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 ultrafast soft recovery minimize ringing
and electrical noise in many power switching circuits
reducing power loss in the switching transistors.
Formerly development type TA49039.
