8A, 400V - 600V Ultrafast Diodes
The RURD840, RURD860, RURD840S and RURD860S are
ultrafast dual diodes with soft recovery characteristics
(t
rr
< 60ns). 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 recti鏗乪rs 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.
Formerly developmental type TA09616.
