RURD460, RURD460S
Data Sheet January 2000
4A, 600V Ultrafast Diodes
The RURD460, and RURD460S are ultrafast diodes with
soft recovery characteristics (t
< 55ns). They have low
rr
forward voltage drop 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 switchingpower
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.
