Data Sheet January 2000 File Number 4050.1
4A, 1200V Ultrafast Dual Diode
The RURP4120CC is an ultrafast dual diode with soft recovery characteristics (trr < 70ns). It has low forward voltage drop and is silicon nitride passivated ion-implanted epitaxial planar construction. This device is intended for use as a freewheeling/clamping diode and rectifier in a variety of switching power supplies and other power switching applications. Its low stored charge and ultrafast soft recovery minimize ringing and electrical noise in many power switching circuits reducing power loss in the switching transistors. Formerly developmental type TA49036.
