FAIRCHILD 2N3642 NPN silicon transistor (NOS gold pin)

The 2N3642 is an NPN silicon transistor designed for small-signal amplification and switching tasks. It features a maximum collector-emitter voltage of 30 V, supports up to 500 mA collector current, and dissipates up to 350 mW of power. With a transition frequency of 250 MHz, it is suitable for high-frequency applications. Packaged in a TO-105 case, the 2N3642 is ideal for legacy circuits requiring reliable performance from discontinued components.
