2N3563 NPN bipolar junction transistor (MIL/SPEC gold leads)

The 2N3563 is an NPN bipolar junction transistor optimized for low-power, very high-frequency (VHF) applications such as RF amplification, oscillation, and switching. Featuring a collector-emitter voltage of 12 V, a maximum collector current of 50 mA, and power dissipation up to 200 mW, it supports DC current gain ranging from 20 to 200 at 8 mA. Its transition frequency reaches 600 MHz, making it ideal for circuits demanding reliable high-frequency performance. Packaged in a TO-106 metal-can for durability, the 2N3563 remains a valuable component despite being considered obsolete by some manufacturers.
