AQ-A
NOTES
Cautions for Use
1. Part number indication
The AQ-J slim heat sink combined type is
a product combining the AQ-J SSR and
AQ-J SSR heat sinks. The part numbers
are indicated on each AQ-J SSR and
heat sink.
Ex) In the case of AQJ112VY
Part number of AQ-J SSR: AQJ112V
Part number of the heat sink: AQP810*
When using these parts, please refer to
REFERENCE DATA, “1. Load current vs.
ambient temperature”.
Note: * The Japanese part number is printed on the
following accessories in stead of Global part
number. Please refer to the below chart for
interpretation from Japanese to Global part
number.

1. Noise and surge protection at the
input side
A high noise surge voltage applied to the
SSR input circuit can cause malfunction
or permanent damage to the device. If
such a high surge is anticipated, use C or
R noise absorber in the input circuit.
2. When the input terminals are
connected with reverse polarity
Reversing the polarity will not cause
damage to the device, due to the
presence of a protection diode, but the
device will not operate.
3. In the case of operating voltage
containing ripple
If the SSR control voltage contains ripple,
the peak of the ripple should not exceed
the maximum rated control voltage (32V),
and the bottom of the ripple should
exceed the minimum rated control
voltage (4V).
4. When used for the load less than
rated at the output side
An SSR may malfunction if it is used
below the specied load. In such an
event, use a dummy resistor in parallel
with the load.
Set a value of dummy resistor so that the
load current becomes 100 mA or more
(AQ-A) or 50 mA or more (AQ-J) due to
the dummy resister and load.
5. Others
1) If an SSR is used in close proximity to
another SSR or heat-generating device,
its ambient temperature may exceed the
allowable level. Carefully plan SSR layout
and ventilation.
2) Terminal connections should be made
by referring to the associated wiring
diagram.
3) When mounting a heat sink, coat it
with a heat conducting compound or
similar in order to improve the heat
dissipation effect.
4) The product is hot during and
immediately after operation. Use caution.
5) When mounting a slim heat sink (AQP-
HS-SJ10A, AQP-HS-SJ20A) on a DIN
rail, mount it as per the instructions in
Note of the dimensional drawing.
Mounting in the opposite direction may
cause disengagement due to vibration or
impact.
6) For higher reliability, check device
quality under actual operating conditions.
6. Transportation and storage
1) Extreme vibration during transport will
warp the terminal or damage the relay.
Handle the carton and case with care.
2) Storage under extreme conditions will
cause external appearance defects, and
deterioration of the characteristics. The
following storage conditions are
recommended:
Temperature: 0 to 45
°C 32 to 113°F
Humidity: Less than 70% R.H.
Atmosphere: No harmful gasses such
as sulfurous acid gas, minimal dust.
