File Number 3640.3
6A, 200V Ultrafast Diodes
Features
The RURD620, and RURD620S are ultrafast diodes with
• Ultrafast with Soft Recovery . . . . . . . . . . . . . . . . . . .<25ns
soft recovery characteristics (t < 25ns). They have low
forward voltage drop and are silicon nitride passivated
ion-implanted epitaxial planar construction.

• Avalanche Energy Rated
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.
