Could you please let me know the θjc and Ψjt of THS9000.

I need it to evaluate as soon as possible.

Thanks

HelloKoji,

I checked our package database and I could not find those parameters for this part. Are you using the DRW package?

I will have to check to see if someone can help me get this information.

Regards,
Loren

Thank you for your prompt reply.

Yes I'm using DRW pckae.

I'd really appreciated if you could continue to confirm this.

I'm looking forward to getting your reply.

Thanks

Hello Koji-san,

I put in a modeling request with our packaging group. The turn around time is two weeks.

Hello Koji-san,

I have not seen the results of my request yet. I will have to check, I have never done a thermal modeling request before, so maybe I am not looking right place for the results.

Loren

Dear Loren-san

I'm really sorry but I would like to know the "unit" of each data.

℃/W ? or ℃ ?

I would like to avoid my miss understand.

I'm really appreciate you support.

Thanks

Hello Koji-san,

The units are in Degrees C per Watt for all of the Theta numbers.

I am not familiar with the Psi units, but they should be in Degrees C per watt as well. Unfortunately the report from the modeling group had no units.

The document below shows units of Degrees C per Watt for all thermal units:
