6A, 200V Ultrafast Dual Diodes
The RURD620CC and RURD620CCS are ultrafast dual
diodes with soft recovery characteristics (t
rr
< 25ns). 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 recti鏗乪rs 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.
