A: The value of R
θJA
is measured with the device mounted on 1in
2
FR-4 board with 2oz. Copper, in a still air environment with T
A
= 25° The
C.
value in any given application depends on the user's specific board design.
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 t
≤
300µs pulses, duty cycle 0.5% max.
C.
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° The SOA
curve provides a single pulse rating.

G. E
AR
and I
AR
ratings are based on low frequency and duty cycles to keep T
