8A, 400V - 600V Ultrafast Diodes
Features
The RURD840, RURD860, RURD840S and RURD860S are
ultrafast dual diodes with soft recovery characteristics

• Operating Temperature. . . . . . . . . . . . . . . . . . . . . . .175 C
(t < 60ns). They have low forward voltage drop and are

• Avalanche Energy Rated
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.
• Planar Construction
Applications
• Switching Power Supplies
• Power Switching Circuits
• General Purpose
Formerly developmental type TA09616.
