30A, 200V Ultrafast Dual Diode
The RURG3020CC is an ultrafast dual diode with soft
recovery characteristics (t
< 45ns). It has low forward
rr
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 recovery with soft recovery characteristics
minimizes ringing and electrical noise in many power
switching circuits reducing power loss in the switching
transistors.
Formerly developmental type TA09645.
