100A, 1200V Ultrafast Diode
The RURU100120 is an ultrafast diode with soft recovery
characteristics (t
rr
< 125ns). It has low forward voltage drop
and is 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 characteristic
minimize ringing and electrical noise in many power
switching circuits, thus reducing power loss in the switching
transistors.
Formally developmental type TA49020.
