RURD620CC, RURD620CCS
Data Sheet January 2000
6A, 200V Ultrafast Dual Diodes
The RURD620CC and RURD620CCS are ultrafast dual
diodes with soft recovery characteristics (t
< 25ns). They
rr
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, thus reducing power loss in the
switching transistors.
Formerly developmental type TA49037.
