But users should care the heat dissipation issue for their applications. The following diagram shows the relation between the package temperatures and power dissipation. Conditions: TO-252 package, Room Temperature: 20°C. The thermal resistance is around 66°C /W, junction to ambient (no air flow) Temperature vs. Power Dissipation 140 Temperature (°C) 120 100 80 60 40 20 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 Power Dissipation (W) Note: Rule of thumb, it is suggested that the IC surface temperature is maintained below 90°C (Celsius degree). For TO-252 package, maintain the power dissipation below 2W. 12 MG39U103-xxx Data Sheet MEGAWIN 10 Package Dimension 10.1 TO-252 Package Dimension 10.2 SOP8 Package Dimension MEGAWIN MG39U103-xxx Data Sheet 13 11 Rev Revision History Descriptions Date V1.01 Initial release. 2011/10/03 V1.02 Add SOP8 package information. 2013/01/17 V1.03 Add 60mA and 70mA output selection 2013/09/17 14 MG39U103-xxx Data Sheet MEGAWIN
