RURD420, RURD420S Data Sheet January 2000 File Number 3614.5 4A, 200V Ultrafast Diodes Features The RURD420 and RURD420S are ultrafast diodes with soft recovery characteristics (trr < 30ns). They have low forward voltage drop and are ion-implanted epitaxial planar construction. • Ultrafast with Soft Recovery . . . . . . . . . . . . . . . . . . . <30ns 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 . . . . . . . . . . . . . . . . . . . . . . . . . . . . .200V • Planar Construction Applications • Switching Power Supplies • Power Switching Circuits Formerly developmental type TA49034. • General Purpose Ordering Information PART NUMBER • Operating Temperature. . . . . . . . . . . . . . . . . . . . . . .175oC PACKAGE BRAND RURD420 TO-251 RUR420 RURD420S TO-252 RUR420 Packaging JEDEC STYLE TO-251 ANODE CATHODE NOTE: When ordering, use the entire part number.
