INSULATION LIFETIME
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of insu-
lation 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 ADuM520x.
Analog Devices performs accelerated life testing using voltage
levels higher than the rated continuous working voltage. Acce-
leration 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 9 summarize the
peak voltage for 50 years of service life for a bipolar ac operating
condition, and the maximum CSA/VDE approved working vol-
tages. In many cases, the approved working voltage is higher than
a 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 ADuM520x depends on the voltage
waveform type imposed across the isolation barrier. The iCoupler
insulation structure degrades at different rates depending on
whether the waveform is bipolar ac, unipolar ac, or dc. Figure 26,
Figure 27, and Figure 28 illustrate these different isolation
voltage waveforms.
Bipolar ac voltage is the most stringent environment. The goal
of a 50-year operating lifetime under the ac bipolar condition
determines the maximum working voltage recommended by
Analog Devices.

In the case of unipolar ac or dc voltage, the stress on the insula-
tion is significantly lower. This allows operation at higher working
voltages while still achieving a 50-year service life. The working
voltages listed in Table 9 can be applied while maintaining 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 27 or Figure 28
should be treated as a bipolar ac waveform and its peak voltage
limited to the 50-year lifetime voltage value listed in Table 9.
The voltage presented in Figure 27 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.
