They have a low forward voltage drop and are of planar, silicon nitride passivated, ion-implanted, epltaxial construction. These devices are intended for use as energy steering/ A 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 characteristics minimizes ringing and electrical noise in many power switching circuits thus reducing power loss in the switching transistor. All are supplied in TO-220AC packages.
