A. The value of RθJA is measured with the device mounted on 1in
2 FR-4 board with 2oz. Copper, in a still air environment with T
A =25°C. The value
in any given application depends on the user's specific board design.
B. The power dissipation P
D is based on TJ(MAX)=150°C, using ≤ 10s junction-to-ambient thermal resistance.
C. Repetitive rating, pulse width limited by junction temperature T
J(MAX)=150°C. Ratings are based on low frequency and duty cycles to keep
initialT
J=25°C.
D. The RθJA is the sum of the thermal impedence from junction to lead RθJL and lead to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300
s pulses, duty cycle 0.5% max.
F. These curves are based on the junction-to-ambient thermal impedence which is measured with the device mounted on 1in2 FR-4 board with 2oz.
Copper, assuming a maximum junction temperature of T
J(MAX)=150°C. The SOA curve provides a single pulse rating.
