PC3H2 Series

■ Design Considerations

● Design guide

While operating at IF<1.0mA, CTR variation may increase.

Please make design considering this fact.

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 IRED 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 IRED.

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.
