The 2N2861 is a silicon bipolar junction transistor (BJT) manufactured by Texas Instruments. It is designed for high-frequency applications, with a transition frequency (fT) of 30 MHz.
Key electrical characteristics include a maximum continuous collector current (IC MAX) of 100 mA and a maximum continuous collector power dissipation (PC MAX) of 300 mW. The collector-emitter breakdown voltage (VCEO) is rated at a minimum of 20V and typically 25V. The static current gain (hFE) is a minimum of 60 under specific test conditions (IC = 1 mA, VCE = 20 V).
This transistor is housed in a TO-18 package and is designed for through-hole mounting. Its specifications make it suitable for various general-purpose amplification and switching applications in electronic circuits where high-frequency performance is required.
