6A, 200V Ultrafast Diodes
The RURD620, and RURD620S are ultrafast 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, reducing power loss in the
switching transistors.
Formerly developmental type TA49037.
