RURD460, RURD460S
4A, 600V Ultrafast Diodes
The RURD460, and RURD460S are ultrafast diodes with
soft recovery characteristics (t
rr
< 55ns). 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 developmental type TA49035.
