1. Reduced package size
Lower surface has been reduced 60%
and mounting space 40% compared to
conventional 4-pin SOP type.
2. Two types are available: A type with
greatly reduced ON resistance, and a
type with even lower output
capacitance between terminals.

CAUTIONS FOR USE
1. Applying stress that exceeds the
absolute maximum rating
If the voltage or current value for any of
the terminals exceeds the absolute
maximum rating, internal elements will
deteriorate because of the excessive
voltage or current. In extreme cases,
wiring may melt, or silicon P/N junctions
may be destroyed.
As a result, the design should ensure that
the absolute maximum ratings will never
be exceeded, even momentarily.
(Use at 15V DC or lower and 9V AC or
lower is recommended.)
2. Deterioration and destruction
caused by discharge of static
electricity
This phenomenon is generally called
static electricity destruction. This occurs
when static electricity generated by
various factors is discharged while the
relay terminals are in contact. The result
can produce internal destruction of the
element.
To prevent problems from static electricity,
the following precautions and measures
should be taken when using your device.
1) Employees handling relays should
6
wear anti-static clothing and should be
grounded through protective resistance of
500 kΩ to 1 MΩ.
2) A conductive metal sheet should be
placed over the work table. Measuring
instruments and jigs should be grounded.
3) When using soldering irons, either use
irons with low leakage current, or ground
the tip of the soldering iron. (Use of low-
voltage soldering irons is also
recommended.)
4) Devices and equipment used in
assembly should also be grounded.
5) When packing printed circuit boards
and equipment, avoid using high-polymer
materials such as foam styrene, plastic,
and other materials which carry an
electrostatic charge.
6) When storing or transporting relays, the
environment should not be conducive to
generating static electricity (for instance,
the humidity should be between 45 and
60%). Relay should always be protected
by using non-conductive packing
materials.
3. Short across terminals
Do not short circuit between terminals
when relay is energized. There is
possibility of breaking the internal IC.
4. Surge voltages at the input
If reverse surge voltages are present at
the input terminals, connect a diode in
reverse parallel across the input terminals
and keep the reverse voltages below the
reverse breakdown voltage.

5. Recommended LED forward current
(I
F
)
It is recommended that the LED forward
current (I
F
) be kept at 5mA.
6. Ripple in the input power supply
If ripple is present in the input power
supply, observe the following:
1) For LED operate current at Emin,
maintain the min. 5mA.
2) Keep the LED operate current at 50
mA or less at E
