RURP3020
30A, 200V Ultrafast Diode
The RURP3020 is an ultrafast diode (t
recovery characteristics. It has a low forward voltage drop
and is of planar, silicon nitride passivated, ion-implanted,
epitaxial construction.
rr
< 45ns) with soft
This device is intended for use as an energy steering/
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 minimize ringing and electrical noise in many
power switching circuits, thus reducing power loss in the
switching transistor.
Formally development type TA09645.
