CAUTIONS FOR USE
1. Please refer to ’03-’04 Solid State
Relays catalog for cautions for use,
explanations about technical terms
and other information.
2. The internal IC could be damaged if
a short forms between the I/O
terminals while the phototriac coupler
is powered.
3. Output spike voltages
1) The figure below shows an ordinary
triac drive circuit. Please add a snubber
circuit or varistor, as noise/surge on the
load side could damage the unit or cause
malfunctions.

6. Cleaning
The phototriac coupler forms an optical
path by coupling a light-emitting diode
(LED) and photodiode via transparent
silicon resin. For this reason, 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 0.25 W/cm
2
• Cleaning time:
No longer than 30 seconds
• 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.

2) Even if spike voltages generated at the
load are limited with a clamp diode if the
circuit wires are long, spike voltages will
occur by inductance. Keep wires as short
as possible to minimize inductance.
4. Ripple in the input power supply
1) For LED operate current at E
min
,
maintain min. 10 mA
2) Keep the LED operate current at 50 mA
or less at E
max
.
7. Soldering
1) When soldering PC board terminals,
keep soldering time to within 10 seconds
at 260°C
500°F.
2) When soldering surface-mount
terminals, the following conditions are
recommended.
(1) IR (Infrared reflow) soldering method

(4) Soldering iron method
Tip temperature: 280 to 300°C

Wattage: 30 to 60 W
Soldering time: within 5 seconds
(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.

5. Important Notes for Mounting
Temperature rise in the lead portion is
highly dependent on package size. If
multiple different packages are mounted
on the same board, please check your
board beforehand in an actual product,
ensuring that the temperature conditions
of the phototriac coupler fall within the
parameters listed above.
