RθJC(bot)Junction-to-case (bottom) thermal resistance—°C/W
(1) The value of RθJA given in this table is only valid for comparison with other packages and can not be used for design purposes. This value was calculated in accordance with JESD 51-7, and simulated on a 4-layer JEDEC board when PDP = 129 mW, PDC = 142 mW and PDT = 129 mW. The board temperature is taken from Pin 12.
