A: The value of R
θ
JA
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
Power dissipation P
DSM
is based on R
θ
JA
and the maximum allowed junction temperature of 150°C. The value in any given application depends on
the user's specific board design, and the maximum temperature of 175°C may be used if the PCB allows it.
B. The power dissipation P
D
is based on T
J(MAX)
=175°C, using junction-to-case thermal resistance, and is more useful in setting the upper
dissipation limit for cases where additional heatsinking is used.
C: Repetitive rating, pulse width limited by junction temperature T
J(MAX)
=175°C.
D. The R
θ
JA
is the sum of the thermal impedence from junction to case R
θ
JC
and case to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300
μ
s pulses, duty cycle 0.5% max.
F. These curves are based on the junction-to-case thermal impedence which is measured with the device mounted to a large heatsink, assuming a
maximum junction temperature of T
J(MAX)
=175°C.
G. The maximum current rating is limited by bond-wires.
H. 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.
