CAUTIONS FOR USE
SAFETY WARNINGS
• Do not use the product under conditions
that exceed the range of its
specifications. It may cause overheating,
smoke, or fire.
• Check the connection diagrams in the
catalog and be sure to connect the
terminals correctly. Erroneous
connections could lead to unexpected
operating errors, overheating, or fire.
• Do not touch the recharging unit while
the power is on. There is a danger of
electrical shock. Be sure to turn off the
power when performing mounting,
maintenance, or repair operations on the
device (including connecting parts such
as the terminal board and socket).
1. Please visit our Automation Controls Products web site
and refer to the caution for use and the explanations of
technical terms.
6. Ripple in the input power supply
If ripple is present in the input power supply, please keep the
LED forward current from 10 (at Emin) to 16 mA(at Emax).
2. About derating design
Derating is significant factor concerning on reliable design
(product life). When the coupler is used continuously at upper
limit of absolute maximum ratings (high temperature, high
humidity, high current, high voltage, etc.), reliability may be lower
significantly. Therefore, please derate sufficiently below the
absolute maximum ratings and evaluate the coupler under the
actual condition.
7. Caution for applying supply voltage
Just after supplying voltage, please note that current in the
coupler will be not constant until circuit stability.
3. Wire connection
Please check the internal connection diagram in the catalog or
specification, and connect the terminals correctly. If device is
energized with short-circuit or any wrong connection, it may
cause circuit damage by inner parts destruction, unexpected
malfunction, abnormal heat, fire, and so on.
8. Soldering
(1) IR (Infrared reflow) soldering method
In case of automatic soldering, following conditions should be
observed.
(recommended condition
reflow: Max. 2 times, measurement point: soldering lead)
4. Bypass capacitor
Bypass capacitor of 0.1μF is used between Vcc and GND near
the coupler. Also, ensure that the distance between the leads of
the coupler and capacitor is no more than 10 mm. Failure to
provide the bypass may impair the switching property.
T3
5. Deterioration and destruction caused by discharge of
static electricity
This phenomenon is generally called static electricity
destruction, and occurs when static electricity generated by
various factors is discharged while the coupler terminals are in
contact, producing 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 the coupler should 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
worktable. 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 the coupler, the environment
should not be conducive to generating static electricity (for
instance, the humidity should be between 45 and 60 %), and the
coupler should be protected using conductive packing materials.

(2) Others soldering methods
Other soldering methods (VPS, hot-air, hot plate, laser heating,
pulse heater, etc.) affect the coupler characteristics differently,
please evaluate the coupler under the actual usage.
(3) Manual soldering method
Soldering: Max. 350 °C 662 °F, within 3 s, electrical power 30 to
60 W
9. Notes for mounting
(1) When different kinds of packages are mounted on PCB, the
temperature rise at soldering lead is highly dependent on
package size. Therefore, please set the lower temperature
soldering condition than above condition, and confirm the
temperature condition of actual usage before soldering.
(2) When soldering condition is out of recommendation, the
coupler characteristics may be adversely affected. It may occur
package crack or bonding wire breaking because of thermal
expansion unconformity and resin strength reduction. Please
contact us about the propriety of the condition.
(3) Please confirm the heat stress by using actual board
because it may be changed by board condition or manufacturing
process condition.
(4) Solder creepage, wettability, or soldering strength will be
affected by the soldering condition or used solder type. Please
check them under the actual production condition in detail.
(5) Please apply coating when the coupler returns to the room
temperature.

PhotoIC Coupler 50 Mbps type (APS1)
10. Cleaning solvents compatibility
Cleaning the solder flux should use the immersion washing with
an cleaning solvent (Asahiklin AK-225). If you have to use
ultrasonic cleaning, please adopt the following conditions and
check that there are no problems in the actual usage.
• Frequency: 27 to 29 kHz
• Ultrasonic output: No greater than 0.25 W/cm2*
• Cleaning time: 30 s or less
• Others: Float PCB and the device in cleaning solvent to prevent
from contacting the ultrasonic vibrator.
*Note: Applies to unit area of ultrasonic output for ultrasonic baths.
11. Transportation and storage
(1) Extreme vibration during transport may deform the lead or
damage the coupler. Please handle the outer and inner boxes
with care.
(2) Inadequate storage condition may degrade soldering,
appearance and characteristics.
The following storage conditions are recommended:
• Temperature: 0 to 45 °C 32 to 113 °F
• Humidity: Max. 70 %RH
• Atmosphere: No harmful gasses such as sulfurous acid gas
and not dusty.
(3) In case the heat stress of soldering is applied to the coupler
which absorb moisture inside of its package, the evaporation of
the moisture increases the pressure inside the package and it
may cause the package blister or crack. This coupler is sensitive
to moisture and it is packed in the sealed moisture-proof
package. Please make sure the following condition after
unsealing.
*Please use the coupler immediately after unsealing. (within 30
days at 0 to 30 °C 32 to 86 °F and Max. 70%RH)
*If the coupler will be kept for a long time after unsealing, please
pack in the another moisture-proof package containing silica gel
and store. (Please use within 90days)
12. Water condensation
Water condensation occurs when the ambient temperature
changes suddenly from a high temperature to low temperature
at high humidity, or the coupler is suddenly transferred from a
low ambient temperature to a high temperature and humidity.
Condensation causes the failures such as insulation
deterioration. Panasonic Corporation does not guarantee the
failures caused by water condensation.
The heat conduction by the equipment the coupler is mounted
may accelerate inside equipment water condensation. Please
confirm no that there are condensation in the worst condition of
the actual usage.
(Special attention should be paid when high temperature heating
parts are close to the coupler.)
