Additional Details

The 2SC5612 is characterized by a low noise figure, typically around 1.0 dB, and a high gain, often reaching 15 dB or more at VHF/UHF frequencies. It typically has a collector-emitter voltage (VCEO) of about 15V and a collector current (IC) of around 30mA. The device is commonly available in a small signal package such as SOT-23. Its low noise and high gain characteristics make it a preferred choice for RF engineers designing sensitive receiver circuits. The transistor also provides stable performance over a wide range of operating conditions. It is designed to minimize internal feedback capacitance to maintain stability and prevent oscillation.
