Notes: 1. The value of θJA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air
environment with TA=25°C. The Power dissipation PDSM is based on θJA and the maximum allowed
junction temperature of 150°C. The value in any given application depends on the user's specific board
design, and the maximum temperature of 175°C may be used if the PCB allows it.
2. The power dissipation PD is based on TJ(MAX)=175°C, using junction-to-case thermal resistance, and is
more useful in setting the upper dissipation limit for cases where additional heatsinking is used.
3. Repetitive rating, pulse width limited by junction temperature TJ(MAX)=175°C. Ratings are based on low
frequency and duty cycles to keep initial TJ=25°C.
4. The θJA is the sum of the thermal impedance from junction to case θJC and case to ambient.
