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.
Please check the internal connection diagram in the catalog or specification, and connect the terminals correctly. If device in 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.
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.
Please connect pull up resistor between Vo and Vcc. The pull up resistor affects the coupler transfer characteristics. Therefore, please evaluate the coupler under the actual condition.
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.
If ripple is present in the input power supply, please keep the LED forward current from 6 (at Emin) to 12 mA (at Emax).
If ripple is present in the input power supply, please keep the LED forward current from 10 (at Emin) to 16 mA (at Emax).
Just after supplying voltage, please note that current in the coupler will be not constant until circuit stability.
In case of automatic soldering, following conditions should be observed.
(recommended condition reflow: Max. 2 times, measurement point: soldering lead)
T1 = 150 to 180 °C 302 to 356 °F
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.
Soldering: Max. 350 °C 662 °F, within 3 s, electrical power 30 to 60 W
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.
* Note: Applies to unit area of ultrasonic output for ultrasonic baths.
The following storage conditions are recommended:
* 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)
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.)
