Thermal Properties
Junction-to-Ambient Thermal Resistance (θ_JA), for 4 layer board⁽¹⁾
Micro SMD 9
70°C/W
(1) Junction-to-ambient thermal resistance is highly application and board-layout dependent. In applications where high maximum power
dissipation exists, special attention must be paid to thermal dissipation issues in board design.
