Power dissipation:

Power dissipation:The power dissipated in the transistor is the voltage drop across the collector emitter junction times the collector current (neglecting the base current times the 0.75V base emitter drop). In the linear range this could be something like 6V@100mA = 600mW (a lot for a little transistor).
