RURD460, RURD460S Data Sheet January 2000 File Number 3140.4 4A, 600V Ultrafast Diodes Features The RURD460, and RURD460S are ultrafast diodes with soft recovery characteristics (trr < 55ns). They have low forward voltage drop and are silicon nitride passivated ionimplanted epitaxial planar construction. • Ultrafast with Soft Recovery . . . . . . . . . . . . . . . . . . . <55ns 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 . . . . . . . . . . . . . . . . . . . . . . . . . . . . .600V • Planar Construction Applications • Switching Power Supplies • Power Switching Circuits Formerly developmental type TA49035. • General Purpose Ordering Information PART NUMBER • Operating Temperature. . . . . . . . . . . . . . . . . . . . . . .175oC PACKAGE BRAND RURD460 TO-251 RUR460 RURD460S TO-252 RUR460 Packaging JEDEC STYLE TO-251 ANODE CATHODE NOTE: When ordering, use the entire part number.
