Apr 24, 2017 · Transistors are typically described as power or small-signal, dependent on the value of this rating. Power transistors typically can dissipate a watt or more of power, while small-signal ones dissipate less than a watt. The maximum dissipation for a 2N3904 is 350 mW (milliwatts), and so it is classified as small signal.
It looks from the datasheet that the 2n9013 has twice the Ic (continuous collector current) of 500mA, compared to a peak in the 3904 of 200mA. The 3904 is definitely intended to be a signal amplifier, and has a gain bandwidth product of 300MHz.
