8A, 400V - 600V Ultrafast Diodes
The MUR840, MUR860, RURP840 and RURP860 are low
forward voltage drop ultrafast recovery rectifiers (t
They use a glass-passivated ion-implanted, epitaxial
construction.
rr
< 60ns).
These devices are intended for use as output rectifiers and
flywheel diodes in a variety of high-frequency pulse-width
modulated switching regulators. Their low stored charge and
attendant fast reverse-recovery behavior minimize electrical
noise generation and in many circuits markedly reduce the
turn-on dissipation of the associated power switching
transistors.
Formerly developmental type TA09616.
