6A, 200V Ultrafast Dual Diodes

The RURD620CCS9A_F085 are ultrafast dual

diodes with soft reco

very 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.
