(1) The junction-to-ambient thermal resistance under natural convection is obtained in a simulation on a JEDEC-standard, High-K board, as specified in JESD51-7, in an environment described in JESD51-2a.

(2) The junction-to-case (top) thermal resistance is obtained by simulating a cold place test on the package top. No specific JEDEC-standard test exists, but a close description can be found in the ANSI SEMI standard G30-88.

(3) The junction-to-board thermal resistance is obtained by simulating in an environment with a ring cold place fixture to control the PCB temperature, as described in JESD51-8.
