■ 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.
