Notes:
1.
Junction-to-ambient thermal resistance is based on measurements on a horizontal single-sided printed circuit board per
JEDEC Specification JESD51-3.
2.
Junction-to-case thermal resistance is based on measurements using a cold plate per SEMI G30-88, with the exception that
the cold plate temperature is used for the case temperature.
3.
These are simulated values. See note 1 for test board conditions.
4.
These are simulated values. The test board has two 2-ounce signal layers and two 1-ounce solid ground planes internal to the
test board.
