  • Power switching circuits 40A, 350V Ultrafast Rectifier The FFA40UP35S is utrafast rectifier with low forward voltage drop. It is silicon nitride passivated ion-implanted epitaxial planar construction. This device is intended for use as freewheeling/clamping rectifi- ers in a variety of switching power supplies and other power swithching applications. Its low stored charge and hyperfast soft recovery minimize ringing and el ectrical noise in many power switching circuits reducing power loss in the switching transis- tors.
