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 electrical noise in many power
switching circuits reducing power loss in the switching transis-
tors.
