Hi, I have a question about the CMOS Op-Amp TSV630. The package is SOT-23-6, but I can't find the pin#1 marking. How can I recognize pin#1 ?

Welcome, @HIwas.3​, to the community!

usually pin 1 is marked with a small dimple.

The housing of the TSV630ILT in SOT23-6 should also have the marking "K108", whereby pin 1 is at the bottom left if you read this text normally in the top view.

Thank you Peter.

I understood Pin 1 as the bottom left of "K108".

However, when I magnified the surface of the IC with a microscope, I could not find the small dimple in the Top View.
