Part Number:TL431A
Dear
I Used TL431ACDBZR in my design.
In data sheet told, there is some marking code for this part. TAC3, TACS , ...
The marking code of the chip that I designed my board with, was TACS.
after production, I saw failure in this part. I have checked the marking code and it was TAC3.
I compared these to parts ( TAC3 and TACS). It seems the input current of Vref pin are difference.
really, Is there any difference?
if there is difference, why the part number is the same?
Best Regards,
Hamidreza
