CSD18542KTT: RθJC

Masakazu Adachi

Part Number: CSD18542KTT

Hello team,

I have a question.

What conditions did you use to measure RθJC? I don't know what kind of substrate and heat sink you used like other FETs, so please let me know.

Regards,

Hello Masa-san,

Thanks for the inquiry. Thermal resistance testing for our D2PAK and TO220 packages is done with the FET attached to a heatsink. I am trying to get more details on the heatsink used for the testing. Unlike other SMT packages, thermal testing is not done with the D2PAK device PCB mounted. Please go to the link below for more information on how TI tests and specs thermal resistance in the datasheet. I'll update you when I have more information.
