APPLICATIONS INFORMATION
deployment
These devices are two terminal overvoltage protectors. They may be used either singly to limit the voltage
between two conductors (Figure 12) or in multiples to limit the voltage at several points in a circuit (Figure 13).
In Figure 12, protector Th1 limits the maximum voltage between the two conductors to ±V
(BO)
. This
configuration is normally used to protect circuits without a ground reference, such as modems. In Figure 13,
protectors Th2 and Th3 limit the maximum voltage between each conductor and ground to the ±V
(BO)
of the
individual protector. Protector Th1 limits the maximum voltage between the two conductors to its ±V
(BO)
value. If the equipment being protected has all its vulnerable components connected between the conductors
and ground, then protector Th1 is not required.
impulse testing
To verify the withstand capability and safety of the equipment, standards require that the equipment is tested
with various impulse wave forms. The table below shows some common values.
If the impulse generator current exceeds the protectors current rating then a series resistance can be used to
reduce the current to the protectors rated value and so prevent possible failure. The required value of series
resistance for a given waveform is given by the following calculations. First, the minimum total circuit
impedance is found by dividing the impulse generators peak voltage by the protectors rated current. The
impulse generators fictive impedance (generators peak voltage divided by peak short circuit current) is then
subtracted from the minimum total circuit impedance to give the required value of series resistance. In some
cases the equipment will require verification over a temperature range. By using the rated waveform values
from Figure 11, the appropriate series resistor value can be calculated for ambient temperatures in the range
of -40 °C to 85 °C.
