THERMAL ANALYSIS
ADuM6400/ADuM6401/ADuM6402/ADuM6403/ADuM6404
Bipolar ac voltage is the most stringent environment. The goal
The ADuM640x devices consist of four internal silicon die
attached to a split lead frame with two die attach paddles. For
the purposes of thermal analysis, the device is treated as a thermal
unit with the highest junction temperature reflected in the θ JA
value from Table 14. The value of θ JA is based on measurements
taken with the part mounted on a JEDEC standard 4-layer board
with fine width traces and still air. Under normal operating
conditions, the ADuM640x operates at full load across the full
temperature range without derating the output current. How-
ever, following the recommendations in the PCB Layout section
decreases the thermal resistance to the PCB, allowing increased
thermal margin at high ambient temperatures.
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 life-
time of the insulation structure within the ADuM640x devices.
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 20 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
the 50-year service life voltage. Operation at these high working
voltages can lead to shortened insulation life in some cases.
of a 50-year operating lifetime under the bipolar ac condition
determines the maximum working voltage recommended by
Analog Devices.
In the case of unipolar ac or dc voltage, the stress on the insu-
lation 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 33 or Figure 34 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 33 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.

The insulation lifetime of the ADuM640x devices 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 32, Figure 33, and Figure 34 illustrate these
different isolation voltage waveforms.
