RURP8120
8A, 1200V Ultrafast Diode
The RURP8120 is an ultrafast 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 minimize ringing and electrical
noise in many power switching circuits, thus reducing power
loss in the switching transistors.
Formerly developmental type TA49095.
