1. Estimates derived from thermal simulation; actual values depend on the application.

2. Theta_JL (QJL): Thermal resistance between the semiconductor junction and the bottom surface of all the leads (including any thermal pad)

that are typically soldered to a PCB.

3. Theta_JT (QJT): Thermal resistance between the semiconductor junction and the top surface of the package, assuming it is held at a uniform

temperature by a top-side heatsink.

4. Theta_JA (QJA): Thermal resistance between junction and ambient, dependent on the PCB design, heat sinking, and airflow. The value given

is for natural convection with no heatsink using a 2S2P board, as specified in JEDEC standards JESD51-2, JESD51-5, and JESD51-7, as

appropriate.

5. Psi_JB (YJB): Thermal characterization parameter providing correlation between semiconductor junction temperature and an application

circuit board reference point for the thermal environment defined in Note 4. For the SOIC-8-EP package, the board reference is defined as

the PCB copper connected to the thermal pad and protruding from either end of the package. For the SOIC-8 package, the board reference

is defined as the PCB copper adjacent to pin 6.

6. Psi_JT (YJT): Thermal characterization parameter providing correlation between the semiconductor junction temperature and the center of

the top of the package for the thermal environment defined in Note 4.
