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 T =25°C. The
A
value in any given application depends on the user's specific board design.
B. The power dissipation P
D
is based on T
J(MAX)
=150°C, using
≤
10s junction-to-ambient thermal resistance.
C. Ratings are based on low frequency and duty cycles to keep initialT
J
=25°C.
D. The R
θJA
is the sum of the thermal impedence from junction to lead R and lead to ambient.
θJL
E. The static characteristics in Figures 1 to 6 are obtained using <300 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 1in 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.
