SOLID STATE RELAY
AQ8-RELAYS
5. High dielectric strength: 3,000 V AC
(between input and output)
6. Two kinds of terminals distance are
available. (5.08 mm and 7.62 mm)
(.200 and .300 inch)
7. High reliability, long life and main-
tenance-free
UL File No.: E95895
CSA File No.: LR26550
FEATURES
1. So slim with 9 mm
.354 inch
thick-
ness
The thin type (45 mm long
×
24 mm high
×
9 mm wide)
(1.772
×
.945
×
.354 inch)
permits high density mounting.
2. Excellent in noise resistance
Since the input and output are insulated
by the photo TRIAC coupler, the noise
on the output side is not fed back to the
input side.
3. Snubber circuit integrated
The snubber circuit is integrated to pre-
vent malfunction caused by the rapid rise
of the voltage on the output side, such as
inductive load and noise.
4. Zero-cross and nonzero-cross
types are available.
The zero-cross type generates minimal
noise by suppressing occurrence of radio
frequency interference (RFI) and electro-
magnetic interference (EMI).
The nonzero-cross type features a short
operation time which permits phase con-
trol.

NOTES
1. When used for the load less than
rated
In case of the load current less than
rated, malfunction may result from the
residual voltage across the both ends of
the load even if the solid state relay is
turned off. Use a dummy resistor as a
countermeasure.
The total of the current through the resis-
tor and the load current must exceed the
min. rated load current.
2. Solder the terminals within 5
seconds at 260°C
500°F.
3. when the terminal is bent
Care shall be taken neither to apply
mechanical stresses to the mold area of
the solid state relay nor to bend the ter-
minal 45 degrees or more.

In case the dummy resistor is not used,
keep in mind that the residual voltage
becomes as follows:
Example:
For the inductive load by the 20 mA load
current and the 200 V AC load voltage, the
load impedance becomes 10 kΩ and Ve/V
= 14% is estimated from the right above
graph. Accordingly, the 28 V voltage
remains across the both ends of the load
when the solid state relay is turned off.
