Additional Details:

The 2SC4095 typically comes in a small surface-mount package such as SOT-23 or similar. The collector-emitter voltage (VCEO) is generally around 20V, and the collector current (IC) is typically in the tens of milliamperes range. The transition frequency (fT) is usually in the GHz range, making it ideal for VHF and UHF applications. It's designed to provide stable oscillation and high gain at these frequencies. This transistor requires careful impedance matching and biasing to achieve optimal performance in oscillator and amplifier circuits. It is commonly used in applications where a stable, high-frequency signal is required, such as in wireless communication devices and radar systems.
