The FFPF60SA60DSTU is a STEALTH™ Dual Series Diode offers soft recovery characteristics. It is silicon nitride passivated ion implanted epitaxial planar construction. This device is intended for use as freewheeling of boost diode in switching power supplies and other power switching applications. Their low stored charge and Hyperfast soft recovery minimize ringing and electrical noise in many power switching circuits reducing power loss in the switching transistors.
