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.
B. The power dissipation P
D
is based on T
J(MAX)
=150
°
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. Single
pulse width limited by junction temperature T
J(MAX)
=150
°
C.
D. The R
θ
JA
is the sum of the thermal impedance 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 impedance which is measured with the device mounted to a large heatsink, assuming
a maximum junction temperature of T
J(MAX)
=150
°
C. The SOA curve provides a single pulse rating.
G. The maximum current rating is package limited.
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.
