4A, 600V Ultrafast Diodes
Features
The RURD460, and RURD460S are ultrafast diodes with soft
• Ultrafast with Soft Recovery. . . . . . . . . . . . . . . . . . . <55ns
recovery characteristics (t < 55ns). They have low forward
voltage drop and are silicon nitride passivated ion-implanted
epitaxial planar construction.

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.
