RΘJC | Junction-to-case | 8.5 |
RΘJB | Junction-to-board | 6.2 |
RΘJA | Junction-to-free air | 24.7 |
PsiJC | Junction-to-package top | 0.36 |

(2) °C/W = degrees Celsius per watt.
(3) These values are based on a JEDEC-defined 2S2P system (with the exception of the Theta JC [RΘ
JC] value, which is based on a JEDEC-defined 1S0P system) and will change based on environment as well as application. For more information, see these EIA/JEDEC standards:
