RURD6120, RURD6120S

Data Sheet January 2000

6A, 1200V Ultrafast Diodes

The RURD6120 and RURD6120S are ultrafast diodes with
soft recovery characteristics (t

< 70ns). They have low

rr

forward voltage drop and are silicon nitride passivated ion­implanted epitaxial planar construction.

These devices are intended for use as freewheeling/
clamping diodes and rectifiers in a variety of switchingpower
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 development type TA49039.
