2N2484 Temperature-Power Derating Curve
Use the Graph to determine how much to derate power [wattage] based on ambient operational temperature [Ta]. The chart indicates that 2000C is the maximum ambient operating temperature for a 2N2484. There are three different curves for the 2N2484 in the graph. The top curve is a not to exceed or damage to the 2N2484 will result. The curve below that represents the maximum operating limits of the 2N2484. While the bottom two gray curves show the correct derating of the 2N2484, with the lowest curve providing the longest life for the 2N2484.
Transistor Derating Curves
Temperature-Power derating is a standard design practice for electrical engineers.
