Hi,
Can someone help me to identify this optocoupler. There are six of these in PowerFlex 755 125HP drive.
Marked on component - "R9905 N250
"
Searching 9905 for an optocoupler, I found part number 559-PS9905-Y-V-F3-AXCT-ND.
The Datasheet shows the first row is an R for the Company Initial. The second row is 9905 for the Type Number. The third line will the for the Assembly Lot. The breakdown is N=Rank Code, 2=Last digit of the assembled year (2022, 2012, 2002,…), and the 50 is the week it was assembled (Mid December).
