4A, 200V Ultrafast Diodes
The RURD420 and RURD420S are ultrafast diodes with soft
recovery characteristics (t
voltage drop and are 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.
Formerly developmental type TA49034.
Ordering Information
NOTE: When ordering, use the entire part number. Add the suffix 9A
to obtain the TO-252 variant in tape and reel, i.e., RURD42059A.
