Junction to Ambient (natural convection)1, 2

1 Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site (board)

temperature, ambient temperature, air flow, power dissipation of other components on the board, and board thermal

resistance.

2 Per JEDEC JESD51-2 with the single layer board horizontal. Board meets JESD51-9 specification.
