The MUR1660CT 16A, 600V Ultra fast Diodes have a low forward voltage drop and are of planar, silicon nitride passivated, ion-implanted, epitaxial construction. These devices are intended for use as energy steering/clamping diodes and rectifiers in a variety of switching power supplies and other power switching applications. Their low stored charge and ultra fast recovery with soft recovery characteristics minimizes ringing and electrical noise in many power switching circuits, thus reducing power loss in the switching transistor. These state-of-the-art devices are a series designed for use in switching power supplies, inverters and as free wheeling diodes.
