MUR840, MUR860, RURP840, RURP860
8A, 400V - 600V Ultrafast Diodes
The MUR840, MUR860, RURP840 and RURP860 are low
forward voltage drop ultrafast recovery rectifiers
(trr < 60ns). They use a glass-passivated ion-implanted,
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.

ta = Time to reach peak reverse current (See Figure 9).
tb = Time from peak IRM to projected zero crossing of IRM based on a straight line from peak IRM through 25% of IRM (See Figure 9).
QRR = Reverse recovery charge.
CJ = Junction Capacitance.
RθJC = Thermal resistance junction to case.
pw = pulse width.
D = duty cycle.
