RURD4120, RURD4120S Data Sheet January 2000 File Number 3641.3 4A, 1200V Ultrafast Diodes Features The RURD4120 and RURD4120S are ultrafast diodes with soft recovery characteristics (trr < 70ns). They have low forward voltage drop and are silicon nitride passivated ion-implanted epitaxial planar construction. • Ultrafast with Soft Recovery . . . . . . . . . . . . . . . . . . . <70ns 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 ultrafast 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 developmental type TA49036. • General Purpose Ordering Information PART NUMBER • Operating Temperature. . . . . . . . . . . . . . . . . . . . . . .175oC PACKAGE BRAND RURD4120 TO-251 UR4120 RURD4120S TO-252 UR4120 Packaging JEDEC STYLE TO-251 ANODE CATHODE NOTE: When ordering, use the entire part number.
