MUR840, MUR860, RURP840, RURP860
8A, 400V - 600V Ultrafast Diodes
The MUR840, MUR860, RURP840 and RURP860 are low
forward voltage drop ultrafast recovery rectifiers
(t
rr
epitaxial construction.
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.
