Question:

How can I check the CTR rank when receiving delivery of a photocoupler?

Answer:

The CTR rank is not marked on the semiconductor device, rather it is marked on the box label under "(Z)S/NO:". In the example below, the rank is indicated by the first letter, K (K rank). The other letters and numbers indicate an internal management number.
