2 posts / 0 new

Hello Everyone,

I am planning to make a product where TNY and TOP Switch is required. The number is TNY268PN and TOP257PN. However, The ICs which are procured from the vendor has a date code. For the TNY268PN is showing 2014 and 2017 date code, where as the TOP257PN showing date code of 2007. Is ti ok to use the 2007 manufactured IC in the design I am creating in 2019?

Hi,

Thank you for considering Power Integrations for your solution.

I would recommend using a more recent date code for the TOP257PN part (2010 onwards) for your solution as this would give you a part which has incorporated a lot of improvements over time.

Hope this helps
