Hi team,
Is the maximum junction temperature in the datasheet (125C) just for the non-automotive device or also for automotive, -Q1 device?
Thanks,
Jacob

Jacob,
Thanks for reaching out to the E2E forum.
The max junction temp of 125C only applies to the non-automotive devices; the -Q1 variant can support up to 125C Ambient air temps.

Hi Matthew,
Is there a specified maximum junction temperature for the -Q1 device then? Is it 150C?
Thanks,
Jacob
Jacob,
I'll need to check with some of the chip/design team to see what the right number is here.
Based on the thermals I don't think the junction would ever see more than ~132C at the worst case if Tamb = 125C. I'll see if I can get a more solid answer by tomm.

Matthew
Hi Matthew,
If you could check and confirm, that'd be greatly appreciated. Since it isn't in the datasheet, I wanted to make sure.
Thanks,
Jacob
Jacob,
I confirmed that 150C is Tj max for the Q1. So long as you keep Tamb at or below 125C the Tj should not see >142C(I had used the incorrect coeff above, and that assumes a very worst case set of conditions).
