A: The value of R θJA is measured with the device mounted on 1in FR-4 board with 2oz. Copper, in a still air environment with TA =25°C. The Power
dissipation PDSM is based on steady-state R θJA and the maximum allowed junction temperature of 150°C. The value in any a given application
depends on the user's specific board design, and the maximum temperature fo 175°C may be used if the PCB or heatsink allows it.
B. 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. It is used to determine the current rating, when this rating falls below the package limit.
C: Repetitive rating, pulse width limited by junction temperature TJ(MAX)=175°C.
D. The R θJA is the sum of the thermal impedence from junction to case RθJC and case to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300 µs pulses, duty cycle 0.5% max.
F. These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. The SOA curve
provides a single pulse rating.
G. The maximum current rating is limited by the package current capability.
