Hi Kumar,

OPA2137 has issued PCN shown below. The new FAB in OPA2137 has changed and the marking is a part of the changes, see the link below. The differences in molding markings between pre-PCN and post-PCN are shown in the images you found.

C33D indicates the lot number in the new FAB. 47K indicates that the part is manufactured in July, 2024 in the new FAB.

44AD also indicates the lot number for tracking purposes.

If you have other questions, please let us know.

Best,

Raymond
