The 2N2857 is a silicon NPN transistor manufactured by RCA, designed for UHF equipment applications such as low noise amplifiers, oscillators, and mixers. It is housed in a TO-72 package.
Key electrical specifications include a Collector-Emitter Voltage (VCEO) of 15V, a Collector Current (IC) of up to 40mA, and a maximum device dissipation (PD) of 200mW. The transistor exhibits a DC Current Gain (HFE) ranging from 30 to 150 and a Current-Gain Bandwidth Product (fT) of 1.6 GHz at 5mA IC.
Functional characteristics include a Maximum Unilateral Gain (GU max) of 13dB typical at 500 MHz and a Maximum Available Gain (MAG) of 13.5dB typical at 500 MHz. The noise figure (NF) is 5.5dB at 500 MHz.
This transistor is suitable for high-frequency applications requiring low noise amplification and stable oscillation or mixing performance.
