RHRD4120, RHRD4120S Data Sheet January 2000 File Number 3626.4 4A, 1200V Hyperfast Diodes Features 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. • Hyperfast with Soft Recovery . . . . . . . . . . . . . . . . . . <60ns 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 • Avalanche Energy Rated • Reverse Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . .1200V • Planar Construction Applications • Switching Power Supplies • Power Switching Circuits Formerly development type TA49056. • General Purpose Ordering Information PART NUMBER • Operating Temperature. . . . . . . . . . . . . . . . . . . . . . .175oC PACKAGE BRAND RHRD4120 TO-251 HR4120 RHRD4120S TO-252 HR4120 NOTE: When ordering, use the entire part number.
