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
A
=25° The

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° using

C.
D. The R
θJA
is the sum of the thermal impedence from junction to lead R
θJL
and lead to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300µs 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
2
FR-4 board with
C.
2oz. Copper, assuming a maximum junction temperature of T
J(MAX)
=150° The SOA curve provides a single pulse ratin g.
