■ Design Considerations
Transistor of detector side in bipolar configuration may be damaged by static electricity due to its minute
design.
When handling these devices, general countermeasure against static electricity should be taken to avoid
breakdown of devices or degradation of characteristics.
● Notes about static electricity
In order to stabilize power supply line, we should certainly recommend to connect a by-pass capacitor of
0.01µF or more between VCC and GND near the device.
In case that some sudden big noise caused by voltage variation is provided between primary and secondary
terminals of photocoupler some current caused by it is floating capacitance may be generated and result in
false operation since current may go through LED or current may change.
If the photocoupler may be used under the circumstances where noise will be generated we recommend to
use the bypass capacitors at the both ends of LED.
The detector which is used in this device, has parasitic diode between each pins and GND.
There are cases that miss operation or destruction possibly may be occurred if electric potential of any pin
becomes below GND level even for instant.
Therefore it shall be recommended to design the circuit that electric potential of any pin does not become
below GND level.
This product is not designed against irradiation and incorporates non-coherent LED.
● Design guide
● Degradation
In general, the emission of the LED used in photocouplers will degrade over time.
In the case of long term operation, please take the general LED degradation (50% degradation over 5 years)
into the design consideration.

■ Manufacturing Guidelines
Reflow Soldering:
Reflow soldering should follow the temperature profile shown below.
Soldering should not exceed the curve of temperature profile and time.
Please don't solder more than twice.
● Soldering Method
Flow Soldering :
Due to SHARP's double transfer mold construction submersion in flow solder bath is allowed under the below
listed guidelines.
Flow soldering should be completed below 270˚C and within 10s.
Preheating is within the bounds of 100 to 150˚C and 30 to 80s.
Please don't solder more than twice.
Hand soldering
Hand soldering should be completed within 3s when the point of solder iron is below 400˚C.
Please don't solder more than twice.
Other notices
Please test the soldering method in actual condition and make sure the soldering works fine, since the impact
on the junction between the device and PCB varies depending on the tooling and soldering conditions.

Solvent cleaning:
Solvent temperature should be 45˚C or below Immersion time should be 3 minutes or less
Ultrasonic cleaning:
The impact on the device varies depending on the size of the cleaning bath, ultrasonic output, cleaning time,
size of PCB and mounting method of the device.
Therefore, please make sure the device withstands the ultrasonic cleaning in actual conditions in advance of
mass production.
Recommended solvent materials:
Ethyl alcohol, Methyl alcohol and Isopropyl alcohol
In case the other type of solvent materials are intended to be used, please make sure they work fine in
actual using conditions since some materials may erode the packaging resin.
● Cleaning instructions
This product shall not contain the following materials.
And they are not used in the production process for this product.
