General Purpose
Description
RURG3070CC, RURG3080CC, RURG3090CC and
RURG30100CC are ultrafast dual diodes with soft recovery
characteristics (t
RR
< 110ns). They have low forward voltage
drop and are silicon nitride passivated ion-implanted epitaxial
planar construction.
These devices are intended for use as freewheel/clamping
diode and rectifiers in a variety of switching power supplies
and other power switching applications. Their low stored
charge and ultrafast recovery with soft recovery characteristic
minimizes ringing and electrical noise in many power switch-
ing circuits reducing power loss in the switching transistors.
