Hi Patrick-san

Sorry, I would like to know your answer ASAP.
I think Tj(max) is 125 degree.

Please confirm it.

Hello Ogane-san,
this is not part of our data sheet. I'm still confirming this with our process engineering team.
I also would assume 125 deg C and I also want to confirm it for you.

Best regards,
Patrick

Hello Ogane-san,
sorry for the additional delay.

After some confirmation: you can assume a max junction temp of 125 deg C.
Calculation from the max current consumption yields about 109 deg C junction in operation.

Best regards,
Patrick

Hi Patrick-san

Thank you for your reply.

I understood Tj(max) is 125 degree. I have one more question. What is the temperature of Ta when you calculated?

Best Regards,
