■ 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.
In phase control applications or where the Phototriac Coupler is being by a pulse signal, please ensure that
the pulse width is a minimum of 1ms.
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 that Sharp Phototriac Couplers incorporate superor dV/dt ratings which can often
eliminate the need for a snubber circuit.
● 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.
