CAUTIONS FOR USE
1. Short across terminals
Do not short circuit between terminals
when relay is energized. There is possi-
bility of breaking the internal IC.
2. Surge voltages at the input
If reverse surge voltages are present at
the input terminals, connect a diode in re-
verse parallel across the input terminals
and keep the reverse voltages below the
reverse breakdown voltage.
5. Output spike voltages
1) If an inductive load generates spike
voltages which exceed the absolute max-
imum rating, the spike voltage must be
limited.
Typical circuits are shown below.

3. Recommended LED forward current
(I
F
)
It is recommended that the LED forward
current (I
F
) be kept at 5mA.
4. Ripple in the input power supply
If ripple is present in the input power sup-
ply, observe the following:
1) For LED operate current at E
min,
main-
tain the value mentioned in the table of
“Note 3. Recommended LED forward cur-
rent (I
F
).”
2) Keep the LED operate current at 50
mA or less at E
max.
Add a CR snubber
circuit to the load
7. Input wiring pattern
This relays, avoid installing the input
(LED side) wiring pattern to the bottom
side of the package if you require the
specified I/O isolation voltage (V
iso
) after
mounting the PC board. Since part of the
frame on the output side is exposed, it
may cause fluctuations in the I/O isolation
voltage.

2) If spike voltages generated at the load
are limited with a clamp diode and the cir-
cuit wires are long, spike voltages will oc-
cur by inductance. Keep wires as short
as possible to minimize inductance.
6. Cleaning solvents compatibility
Dip cleaning with an organic solvent is
recommended for removal of solder flux,
dust, etc. Select a cleaning solvent from
the following table. If ultrasonic cleaning
is used, the severity of factors such as
frequency, output power and cleaning
solvent selected may cause loose wires
and other defects. Make sure these con-
ditions are correct before use. For details,
please consult us.

May not allow the prescribed I/O withstand
voltage (Viso) to be achieved
