9 Application information
The MG39U103 can sustain an input voltage level as high as 350V. 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)

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.
