MT-093: Thermal Design Basics - Analog Devices
www.analog.comA performance comparison for an 8-pin standard SOIC and the ADI Thermal Coastline version is shown in Figure 4. Note that the Thermal Coastline provides an allowable dissipation at 25°C of 1.3 W, whereas a standard package allows only 0.8 W. In the Thermal Coastline heat transferal is increased, accounting for the package's lower θJA. 2.0
