3. Short across terminals
Do not short circuit between I/O terminals
when device is energized, since there is
possibility of breaking of 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.
Power type
5. LED current vs. ambient
temperature characteristics
Please keep the LED current to within the
range given below.
6. Ripple in the input power supply
If ripple is present in the input power
supply, observe the following:
1) Please maintain the LED current at
10 mA for E
min.
2) Please make sure for E
max. is no higher
the LED current at than 50 mA.
7. Spike voltages at the output
1) If an inductive load generates spike
voltages which exceed the absolute
maximum rating, the spike voltage must
be limited.
Power type
2) Even if spike voltages generated at the
load are limited with a clamp diode or
snubber circuit if the circuit wires are
long, spike voltages will occur by
inductance. Keep wires as short as
possible to minimize inductance.
8. Cleaning solvents compatibility
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
(Note)
• Cleaning time: No longer than 30
seconds
• Cleanser used: Asahiklin AK-225
• Other: Submerge in solvent in order to
prevent the PC board and elements
from being contacted directly by the
ultrasonic vibrations.
Note: Applies to unit area ultrasonic output for
ultrasonic baths.
9. Notes for mounting
1) If many different packages are
combined on a single substrate, then
lead temperature rise is highly dependent
on package size. For this reason, please
make sure that the temperature of the
terminal solder area of the PhotoMOS
falls within the temperature conditions
“10. Soldering” before mounting.
2) If the mounting conditions exceed the
recommended solder conditions, resin
strength will fall and the nonconformity of
the heat expansion coefficient of each
constituent material will increase
markedly, possibly causing cracks in the
package, severed bonding wires, and the
like. For this reason, please inquire with
us about whether this use is possible.
10. Soldering
When soldering PC board terminals,
keep soldering time to within 10 seconds
at 260°C 500°F.
• When using lead-free solder, we
recommend a type with an alloy
composition of Sn 3.0 Ag 0.5 Cu. Please
inquire about soldering conditions and
other details.
11. Packing format for relay
Tube packaging
The relays are packaged in a tube so that
pin No. 1 is on the stopper B side.
Observe correct orientation when
mounting them on PC boards.
(Power type)
12. Transportation and storage
1) Extreme vibration during transport will
warp the lead or damage the device.
Handle the outer and inner cartons 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.
• Atmosphere: No harmful gasses such
as sulfurous acid gas, minimal dust.
13. Input LED current (Standard power
type)
For rising and dropping ratio (di/dt) of
input LED current, maintain min. 100
μA/s.
14. Adjacent mounting (Power type)
1) When relays are mounted close
together with the heat-generated devices,
ambient temperature may rise
abnormally. Mounting layout and
ventilation of power type should be
considered.
2) When many power type relays are
mounted close together, load current
should be reduced. (Refer to the date of
“Load current vs. ambient temperature
characteristics in adjacent mounting.”)
