A Word About Thermal Management
Tests of aluminum nitride “SG” 50Ω terminations demonstrate the below power capacities, assuming a thermally conductive
application where the steady-state baseplate temperature of the chip is maintained at or below the values identified in the below table
and the maximum film temperature did not exceed 150°C. The data also shows that the ratio of temperature rise versus power applied
increases with increasing chip size (for a given thickness) so the criteria should be carefully considered when using larger chips. As with
any application, actual performance of these chips will depend on a host of circuit dependent parameters.
