ADuM5200/ADuM5201/ADuM5202
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 ADuM5200 /
ADuM5201 / ADuM5202 .
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 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 ADuM5200 / ADuM5201 /
ADuM5202 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 28, Figure 29, and Figure 30
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.
Data Sheet
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 20 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 29 or Figure 30 should be treated as a bipolar ac waveform
and its peak voltage limited to the 50-year lifetime voltage value
listed in Table 20. The voltage presented in Figure 29 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.
