OPA2333-HT: Reliability FIT data at 200ºC

Part Number: OPA2333-HT

Tool/software:

Hello,

I am Luis Eduardo Pedro Sedeño. I am using your SHKQ and SHKJ components for a high-temperature application and I need the reliability data of the component working at 200ºC. I have checked your website and the FIT calculator but the FIT rate could be only adjusted up to 175ºC. Could we expect that the operation would be the same up to 200ºC, complying with the Arrhenius equation? Also, I have seen a reliability report at 210ºC but the number of samples of the test is too low, and also, I dont see these tests at high temperature are done with the component working, but storage tests and other mechanical tests.

Thank you so much.

Kind regards, Luis Eduardo.

    Hi Luis,

    You may certainly use Arrhenius equation to estimate the FIT at 200C or 210C for the part. The sample size at tested temperature 125C is high and confidence should be better. 

    Below is the capture of the data. It is found in the link below.

    You should be able to derive the accelerated factor from the equation below and estimate the rest of FIT data at 200C.

    Yes, the high temperature ratings are only found in handful of op amps in our catalog. It is not automotive and industrial and/or application norm. And it is tough to make these reliably due to the lack of demand. 

    If you have other questions, please let us know. 

    Best,
