RURP1560
15A, 400V - 600V Ultrafast Diode
The RURP1560 is an ultrafast diode (trr< 55ns) with soft
recovery characteristics. It has a low forward voltage drop
and is of planar, silicon nitride passivated, ion-implanted,
epitaxial construction.
This device is intended for use as an energy
steering/clamping d iode an d recti fier in a v ariet y 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 ci rcuits, thus reducing power loss in
the switching transistor.
Formerly developmental type TA09905.
