FEATURES
1. Protects Circuit from excess current
The short circuit protection function
prevents the continued flow of short
current. After short current is detected,
load current is monitored, and if the load
returns to normal, the relay returns to
normal operation.
2. No need for fuses, polyswitches, or
other protectors
The built-in short circuit protection
function eliminates the need for
overcurrent protectors, reducing
mounting costs and space requirements.
3. High capacity
Can control up to 0.5A (60 VDC) load
current.
TYPICAL APPLICATIONS

What is short circuit protection Non-latch type?
If the load current reaches a
predetermined overcurrent level, the
output-side short circuit protection
function cuts off the load current. It then
monitors the load current, and if it returns
to normal, automatically recovers to
normal relay operation.
In order to operate the short circuit
protection function, ensure that the input
current is at least I
F
= 10 mA.

CAUTIONS FOR USE
1. 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.
2. Unused terminals
The No. 3 and 5 terminal is used with the
circuit inside the relay. Therefore, do not
connect it to the external circuitry with
either connection method A, B or C. (Non-
latch type)
3. It is possible that in-rush current will
be detected as short current, and
oscillation will be initiated. Please
confirm before use.
4. Please avoid exposing the unit to
short status for longer than 24 hours.
Long periods of exposure to short
status could damage the internal IC
(non-latch type only).
5. Short across terminals
Do not short circuit between terminals
when relay is energized. There is
possibility of breaking the internal IC.
6. Output spike voltages
1) If an inductive load generates spike
voltages which exceed the absolute
maximum rating, the spike voltage must
be limited. Typical circuits are shown
below.
Latch type
Non-latch type
2) If spike voltages generated at the load
are limited with a clamp diode and the
circuit wires are long, spike voltages will
occur by inductance. Keep wires as short
as possible to minimize inductance.
7. Ripple in the input power supply
If ripple is present in the input power
supply, observe the following:
2) Keep the LED operate current at E
min
,
maintain min. 5 mA (Latch type), 10 mA
(Non-latch type).
1) For LED operate current 50 mA or less
at E
max
.
8. When soldering terminals, keep
soldering time to within 10 s at 260
C
500
F
.
9. Cleaning solvents compatibility
The PhotoMOS relay forms an optical
path by coupling a light-emitting diode
(LED) and photodiode via transparent
silicon resin. For this reason, unlike other
directory element molded resin products
(e.g., MOS transistors and bipolar
transistors), avoid ultrasonic cleansing if
at all possible. We recommend cleaning
with an organic solvent. If you cannot
avoid using ultrasonic cleansing, please
ensure that the following conditions are
met, and check beforehand for defects.
Frequency: 27 to 29 kHz
Ultrasonic output:
No greater than 0.25W/cm
2
Cleaning time:
No longer than 30 s
Cleanser used: Asahiklin AK-225
Other:
Submerge in solvent in order to prevent
the PCB and elements from being
contacted directly by the ultrasonic
vibrations.
Note: Applies to unit area ultrasonic output for
ultrasonic baths.
10. Transportation and storage
1) Extreme vibration during transport will
warp the lead or damage the relay.
Handle the outer and inner boxes with
care.
2) Storage under extreme conditions will
cause soldering degradation, 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.
Atomosphere: No harmful gasses such
as sulfurous acid gas, minimal dust.
11. Soldering
1) When soldering PC board terminals,
keep soldering time to within 10 s at
260
C
500
F
.
2) When soldering surface-mount
terminals, the following conditions are
recommended.
(1) IR (Infrared reflow) soldering method
(2) Vapor phase soldering method
(3) Double wave soldering method
(4) Soldering iron method
Tip temperature: 280 to 300
C
536 to
572
F
Wattage: 30 to 60 W
Soldering time: within 5 s
(5) Others
Check mounting conditions before using
other soldering methods (hot-air, hot
plate, pulse heater, etc.)
The temperature profile indicates the
temperature of the soldered terminal on
the surface of the PC board. The ambient
temperature may increase excessively.
Check the temperature under mounting
conditions.
The conditions for the infrared reflow
soldering apply when preheating using
the VPS method.
