2N2904 is a PNP silicon transistor (gold lead)

The 2N2904 is a PNP silicon transistor tailored for small-signal amplification and high-speed switching, widely used in military and high-reliability circuits. It supports a maximum collector-emitter voltage of 40 V, collector-base voltage of 60 V, and emitter-base voltage of 5 V. With a continuous collector current rating up to 0.6 A and power dissipation between 0.6 W and 0.8 W, it delivers reliable performance. Its transition frequency of 200 MHz ensures effective switching speed. Packaged in a TO-39 metal can with a three-lead pinout (Emitter, Base, Collector), it is suitable for demanding electronic designs.
