2N4033UB Transistor Temperature Derating Curves
The graph details the maximum allowable power dissipation with increasing ambient temperature for a 2N4033 transistor in a Surface Mount package [UB Case]. Maximum operational power dissipation is achievable at 25C. However above 25C the maximum package dissipation must be reduce to insure that the devices junction temperature remains constant. Decreasing a components operational limits as temperature is increased is called derating.
