2N2484 Surface Mount Package

Use the Graph to determine how much to derate power [wattage] based on ambient temperature. The maximum junction temperature is 2000C.
The point of the graph is to keep the junction temperature below the allowed maximum. Also refer to How to Interpret Transistor Derating Curves.
Transistor Derating Curves
Temperature derating is a standard design practice for electrical engineers.
