Description

RURD410, RURD415, RURD420, RURD410S, RURD415S,

and RURD420S (TA49034) are ultrafast diodes with soft

voltage

drop

and

are

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.
