Design Considerations
While operating at I
F
<1.0mA, CTR variation may increase.
Please make design considering this fact.
This product is not designed against irradiation and incorporates non-coherent IRED.
●
Degradation
In general, the emission of the IRED used in photocouplers will degrade over time.
In the case of long term operation, please take the general IRED degradation (50% degradation over 5years)
into the design consideration.
