■ Design Considerations
In order for the Phototriac to turn off, the triggering current (IF) must be 0.1mA or less.
Please refrain from using these devices in a direct drive configuration. These Phototriac Coupler are
intended to be used as triggering device for main Triacs. Please ensure that the output rating of these
devices will be sufficient for triggering the main output Triac of your choice. Failure to do may result in
malfunctions.
For applications with inductive loads such as motors, please use caution in utilizing a zero crossing type Pho-
totraiac Coupler as this may cause undesired operations due to the phase difference between voltage and
current of load.
For designs that will experience excessive noise or sudden changes in load voltage, please include an
appropriate snubber circuit as shown in the below circuit. Please keep in mind the Sharp Phototriac Coupler
incorporate superrior dV/dt ratings which can eliminate the need for a snubber circuit.
For over voltage protection, a Varistor may be used.
● Degradation
In general, the emission of the IRED used in Phototriac Couplers will degrade over time.
In the case where long term operation and / or constant extreme temperature fluctuations will be applied to
the devices, please allow for a worst case scenario of 50% degradation over 5years.
Therefore in order to maintain proper operation, a design implementing these Phototriac Couplers should
provide at least twice the minimum required triggering current from initial operation.

■ 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 260˚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 3minutes 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 device.
Regulation substances : CFCs, Halon, Carbon tetrachloride, 1.1.1-Trichloroethane (Methylchloroform)
Specific brominated flame retardants such as the PBBOs and PBBs are not used in this product at all.
