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