What is the CTR rank for AC input type photocouplers?

Latest Updated:01/01/2011

Question:

The CTR rank for AC input type photocouplers is not described in the data sheet.
What is the CTR rank for these products?

Answer:

In AC input type photocouplers, there are two LEDs connected in parallel in opposing directions on the input side.
Because of this, discrepancies in the CTR occur more frequently than in general-purpose photocouplers. The CTR rank in any AC input type photocouplers is therefore specified as the All rank (without any segmentations).
