110 / 244 page  7.9 Thermal Resistance Characteristics This section provides the thermal resistance characteristics used on this device. For reliability and operability concerns, the maximum junction temperature of the device has to be at or below the TJ value identified in Recommended Operating Conditions. 7.9.1 Thermal Resistance Characteristics Table 7-2. ALV Package Thermal Resistance Characteristics It is recommended to perform thermal simulations at the system level with the worst case device power consumption. NO. PARAMETER DESCRIPTION °C/W(1) (3) AIR FLOW (m/s)(2) ALV Package T1 RΘJC Junction-to-case 0.98 N/A T2 RΘJB Junction-to-board 3.87 N/A T3 RΘJA Junction-to-free air 12.8 0 T4 RΘJA Junction-to-moving air 9.2 1 T5 8.2 2 T6 7.6 3 T7 ΨJT Junction-to-package top 0.53 0 T8 0.55 1 T9 0.57 2 T10 0.58 3 T11 ΨJB Junction-to-board 3.74 0 T12 3.5 1 T13 3.4 2 T14 3.3 3 (1) These values are based on a JEDEC defined 2S2P system (with the exception of the Theta JC [RΘJC] value, which is based on a JEDEC defined 1S0P system) and will change based on environment as well as application.
