15A, 400V - 600V Ultrafast Diodes
The MUR1540, MUR1560, RURP1540, and RURP1560 are
ultrafast diodes (t
rr
< 55ns) with soft recovery
characteristics. They have a low forward voltage drop and
are of planar, silicon nitride passivated, ion-implanted,
epitaxial construction.
These devices are intended for use as energy
steering/clamping diodes and rectifiers in a variety of
switching power supplies and other power switching
applications. Their low stored charge and ultrafast recovery
with soft recovery characteristics minimizes ringing and
electrical noise in many power switching circuits, thus
reducing power loss in the switching transistor.
Formerly developmental type TA09905.
