Data Sheet January 2000

8A, 400V - 600V Ultrafast Diodes

The MUR840, MUR860, RURP840 and RURP860 are low
forward voltage drop ultrafast recovery rectifiers
(t

< 60ns). They use a glass-passivated ion-implanted,

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.Theirlowstoredchargeand
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.
