RURD840, RURD860, RURD840S, RURD860S Data Sheet January 2000 File Number 4033.1 8A, 400V - 600V Ultrafast Diodes Features The RURD840, RURD860, RURD840S and RURD860S are ultrafast dual diodes with soft recovery characteristics (trr < 60ns). They have low forward voltage drop and are silicon nitride passivated ion-implanted epitaxial planar construction. • Ultrafast 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 ultrafast soft recovery minimize ringing and electrical noise in many power switching circuits reducing power loss in the switching transistors. • Planar Construction Applications Formerly developmental type TA09616. • General Purpose Ordering Information PART NUMBER • Operating Temperature. . . . . . . . . . . . . . . . . . . . . . .175oC • Reverse Voltage Up To . . . . . . . . . . . . . . . . . . . . . . . .600V • Avalanche Energy Rated • Switching Power Supplies • Power Switching Circuits Packaging PACKAGE BRAND RURD840 TO-251 RUR840 RURD860 TO-251 RUR860 RURD840S TO-252 RUR840 RURD860S TO-252 RUR860 JEDEC STYLE TO-251 ANODE CATHODE CATHODE (FLANGE) NOTE: When ordering, use the entire part number.
