6A, 600V Ultrafast Diodes
The RURD660 and RURD660S are ultrafast diodes with soft
recovery characteristics (t
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 TA49038.
Ordering Information
NOTE: When ordering, use the entire part number. Add the suffix 9A
to obtain the TO-252 variant in the tape and reel, i.e., RURD660S9A.
