8A, 400V - 600V Ultrafast Diodes
The MUR840, MUR860, RURP840 and RURP860 are low
forward voltage drop ultrafast recovery recti鏗乪rs
(t
rr
< 60ns). They use a glass-passivated ion-implanted,
epitaxial construction.
These devices are intended for use as output recti鏗乪rs and
鏗倅wheel 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.
