Θja, Θjc and Pd of LT4321HUF#TRPBF

Dear Sir:

I am confirming the Θja, Θjc and Pd of LT4321HUF#TRPBF.
I only find Θja data(Θja=47) now. 
Cloud you provide other data to me?
Thank you very much.

    Hello,

    LT4321 has a thermal resistance, junction to case, θJC = 4.5° C/W. The θJA = 47° C/W you mentioned is based on a JEDEC 4 layer board.

    Please note, LT4321 is an Ideal Diode Controller. As such, it consumes very little power even during full load operation. The junction temperature will be very close to the case temperature.

    Best Regards,

    Eric
