SWITCHING PARAMETERS
A. The value of RθJA 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 PDSM is based on R θJA 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 PD is based on TJ(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 TJ(MAX)=175°C. Ratings are based on low frequency and duty cycles to keep initial TJ
=25°C.
D. The RθJA is the sum of the thermal impedence from junction to case RθJC and case to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300
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 TJ(MAX)=175°C. The SOA curve provides a single pulse rating.
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.
