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 ADuM5401 / ADuM5402 /
ADuM5403 / ADuM5404 devices.
Analog Devices performs accelerated life testing using voltage levels
higher than the rated continuous working voltage. Acceleration
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 20 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 ADuM5401 / ADuM5402 /
ADuM5403 / ADuM5404 devices depends on the voltage wave-
form type imposed across the isolation barrier. The i Coupler
In the case of unipolar ac or dc voltage, the stress on the insulation
is significantly lower. This allows operation at higher working
voltages while still achieving a 50-year service life. The working
voltages listed in Table 20 can be applied while maintaining the
50-year minimum lifetime, provided that the voltage conforms
to either the unipolar ac or dc voltage cases.
Any cross-insulation voltage waveform that does not conform
to Figure 31 or Figure 32 should be treated as a bipolar ac wave-
form and its peak voltage limited to the 50-year lifetime voltage
value listed in Table 20. The voltage presented in Figure 32 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.

insulation structure degrades at different rates depending on
whether the waveform is bipolar ac, unipolar ac, or dc. Figure 30,

Bipolar ac voltage is the most stringent environment. The goal
of a 50-year operating lifetime under the bipolar ac condition
determines the maximum working voltage recommended by
Analog Devices.

1. THE VOLTAGE IS SHOWN AS SINUSOIDAL FOR ILLUSTRATION
PURPOSES ONLY. IT IS MEANT TO REPRESENT ANY VOLTAGE

THE LIMITING VALUE CAN BE POSITIVE OR NEGATIVE, BUT THE
