Data Sheet
INSULATION LIFETIME
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of
insulation degradation is dependent on the characteristics of the
voltage waveform applied across the insulation. In addition to
the testing performed by the regulatory agencies, Analog Devices
carries out an extensive set of evaluations to determine the
lifetime of the insulation structure within the ADuM130x.
Analog Devices performs accelerated life testing using voltage
levels higher than the rated continuous working voltage. Accel-
eration factors for several operating conditions are determined.
These factors allow calculation of the time to failure at the
actual working voltage. The values shown in Table 14 summarize
the peak voltage for 50 years of service life for a bipolar ac
operating condition and the maximum CSA/VDE approved
working voltages. In many cases, the approved working voltage
is higher than the 50-year service life voltage. Operation at these
high working voltages can lead to shortened insulation life in
some cases.
The insulation lifetime of the ADuM130x depends on the
voltage waveform type imposed across the isolation barrier.
The i Coupler insulation structure degrades at different rates
depending on whether the waveform is bipolar ac, unipolar ac,
or dc. Figure 18, Figure 19, and Figure 20 illustrate these
different isolation voltage waveforms, respectively.
Bipolar ac voltage is the most stringent environment. The goal
of a 50-year operating lifetime under the ac bipolar condition
determines the Analog Devices recommended maximum
working voltage.
ADuM1300/ADuM1301
In the case of unipolar ac or dc voltage, the stress on the insu-
lation is significantly lower, which allows operation at higher
working voltages while still achieving a 50-year service life. The
working voltages listed in Table 14 can be applied while main-
taining the 50-year minimum lifetime provided the voltage
conforms to either the unipolar ac or dc voltage cases. Any cross
insulation voltage waveform that does not conform to Figure 19
or Figure 20 should be treated as a bipolar ac waveform, and its
peak voltage should be limited to the 50-year lifetime voltage
value listed in Table 14.
Note that the voltage presented in Figure 19 is shown as sinusoidal
for illustration purposes only. It is meant to represent any voltage
waveform varying between 0 V and some limiting value. The
limiting value can be positive or negative, but the voltage
cannot cross 0 V.
