2N3563 small-signal NPN silicon transistor (NOS gold pin)

The 2N3563 is a small-signal NPN silicon transistor optimized for VHF/RF amplifier applications including oscillators and multipliers. It offers a maximum collector-emitter voltage of 12 V, collector current up to 50 mA, and power dissipation rated at 200 mW. With a transition frequency of 600 MHz and housed in a TO-106 package, it is suitable for high-frequency circuits. However, as an obsolete component, availability may be limited, and seeking a modern equivalent is recommended for new designs. Pricing varies due to its rarity and condition.
