CSD19538Q3A: Rjb(junction-to-board thermal resistance) of 115200000409A(CSD19538Q3A)

Part Number: CSD19538Q3A

Dear Team,

Can you provide Rjb(junction-to-board thermal resistance) of 115200000409A(CSD19538Q3A) to our customer ?

Our customer need to do the thermal simulation. Thanks!

Many Thanks,


  • Hi Jimmy,

    Thanks for promoting TI FETs to your customer. The junction to case thermal impedance, Rθjc in the datasheet is specified to the thermal pad on the bottom of the package and is the same as Rθjb. Please check the blog in the link below for more information on how TI tests and specs thermal impedance of our FETs.

    Best Regards,
