Description
RURU15070, RURU15080 and RURU15090 and RURU150100 are
ultrafast diodes with soft recovery characteristics (t
RR
< 125ns).
They have low forward voltage drop and are silicon nitride passi-
vated ion-implanted epitaxial planar construction.
A
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 recovery with soft recovery characteristic minimizes ring-
ing and electrical noise in many power switching circuits reducing
power loss in the switching transistors.
