8A, 1200V Ultrafast Dual Diode
The RURP8120CC is an ultrafast dual diode with soft
recovery characteristics (t
rr
< 100ns). It has low forward
voltage drop and is of silicon nitride passivated 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. Its low stored charge
and ultrafast soft recovery minimizes ringing and electrical
noise in many power switching circuits, thus reducing power
loss in the switching transistors.
Formerly development type TA49095.
