| RHRD4120, RHRD4120S Data Sheet January 2000 File Number 3626.4 4A, 1200V Hyperfast Diodes The RHRD4120 and RHRD4120S are hyperfast diodes with soft recovery characteristics (trr < 60ns). They have half the recovery time of ultrafast diodes and are silicon nitride passivated ion-implanted epitaxial planar construction. These devices are intended for use as freewheeling/clamping diodes and rectifiers in a variety of 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 Formerly development type TA49056.
