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 show s 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 100 120 140 Power Dissipation (W) Temperature (°C) 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.
