A: The value of R
θJA
is measured with the device mounted on 1 in
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. The current rating is based on the t 10s thermal resistance rating.
B: Repetitive rating, pulse width limited by junction temperature.
C. The R
θJA
is the sum of the thermal impedence from junction to lead R
θJL
and lead to ambient.
D. The static characteristics in Figures 1 to 6 are obtained using <300 µs pulses, duty cycle 0.5% max.
E. These tests are performed with the device mounted on 1 in
2
FR-4 board with 2oz. Copper, in a still air environment with T
A
=25°C. The SOA
curve provides a single pulse rating.
