Additional Details

The 2SC3609 typically features a collector-emitter voltage (VCEO) of around 20V. Its collector current (IC) is rated around 1A. The power dissipation (PC) is typically around 5W. The transition frequency (fT) is in the hundreds of MHz, making it suitable for VHF/UHF applications. The low feedback capacitance ensures stable operation and reduces the risk of oscillation. It is typically packaged in a small plastic package, such as a TO-92 or similar. The high power gain allows for efficient amplification of signals with minimal input power. The epitaxial planar structure provides high reliability and performance. Detailed specifications can be found in the Toshiba datasheet for this part number. This transistor is designed to handle higher power levels compared to small-signal transistors. It is often used in the final stages of RF transmitters to boost the signal power before transmission.
