Posted by: jkaart on 09/26/2022

Hi all,

has Power Integrations ever used a painted dot to mark the first pin?

Is this LNK364PN IC genuine?

Hi,

Good day!

Yes, the marking is correct and the part is genuine. I hope this helps.

Best Regards,

When you have started to mark first pin painted dot instead of dimple mark?

I have an old broken part that is dated 1938 and it's marked by dimple style mark.

Hi,

The pin 1 indicator is mold press dependent. The mold press of some of our manufacturing partners has a pin 1 indention while for this one it does not. This is not a significant change. This particular manufacturing company was added in 2017.

Thanks,
