It is a 0.6-ampere, 60-volt, 400-milliwatt transistor. For the 2N2907, the gainbandwidth product under specified test conditions, or fT, is 200 Megahertz, which is notionally the frequency at which the current gain drops to one. Practical use of a transistor requires that it be used for frequencies much less than fT. At low frequencies, the current gain (beta) is at least 100. The 2N2907 is used in a variety of analog amplification and switching applications.
