Hi, Harry

that is theta JA.

We need to know theta JC resistance.

if any, Please advise me.

Thanks,

Best regards,

Hello Lawrence,

For this device, we do not have theta JC numbers available.

For an estimation of derating, you can use JA resistance as JC is lower, see this app note: Semiconductor and IC Package Thermal Metrics (Rev. C) (ti.com)

If you are searching for more information on thermal behavior, please have a look here: SMT & packaging application notes | Packaging | TI.com

Best regards,
Brigitte
