RURD420S
4A, 200V Ultrafast Diodes
The RURD420S is an ultrafast diode with soft recovery
characteristics (trr
< 30ns). It has low forward voltage drop
and has ion-implanted epitaxial planar construction.
This device is intended for use as a freewheeling/clamping
diode and rectifier in a variety of switching power supplies and
other power switching applications. It’s 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 TA49034.
