RURD620, RURD620S

Data Sheet January 2000

6A, 200V Ultrafast Diodes

The RURD620, and RURD620S are ultrafast diodes with
soft recovery characteristics (t

< 25ns). They have low

rr

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, reducing power loss in the
switching transistors.

Formerly developmental type TA49037.
