OPA4277: OPA4277MDTEP Temperature Cycle/Thermal Shock

Hi Brandon,

That information may be very difficult to find. The OPA4277MDTEP (OPA4277-EP) developments were handled by a different TI division that was disbanded several years ago. We didn't receive any information about how the original qualifications were accomplished.

I have contacted our Quality and Reliability Engineering department and asked if they have any insight into the OPA4277-EP temperature cycling or thermal shock circuits. We'll see if they come back with anything.

Hello Thomas, have you heard back from qual and reliability? I do need to verify the components on our end for our applications; if you may share with us what test setups were performed to verify them that would help us.

Hi Brandon,

If you are asking for specifics temperature cycling and thermal shocks tests, it may be difficult to come by. All the ICs rated in Enhanced Product (-EP) will meet the minimum requirements as shown in the link below. You can find the following information on p.3 of from the TI Components for Space, Avionics and Defense Guide (TI adapts the industrial test standard for the application in these products).

If I am able to assist you with additional information, please let me know.

Hi Thomas,

You had mentioned that "The pre and post electrical tests use the product's standard production tests."; may I have those standard production test setups?

Best,

Brandon
