2SC901

The 2SC901 is a reliable NPN bipolar junction transistor engineered for general-purpose amplification and switching tasks. Its combination of voltage, current and frequency characteristics provides dependable performance across a broad range of electronic circuits, from audio preamplifiers to oscillator and switching stages. Key electrical characteristics include a collector-emitter voltage (Vceo) of 25V, a collector current (Ic) rating of 0.8A, and power dissipation capability up to 0.625W. A gain bandwidth product (fT) of 100MHz supports high-frequency amplification needs, while a low noise figure makes the device especially suitable for audio-frequency preamplifier stages and other signal-processing applications that demand clean, low-distortion amplification. Designed with modern semiconductor techniques to enhance switching speed and minimize signal distortion, the 2SC901 also offers thermal stability for consistent operation across varying temperature conditions. These properties help maintain reliable long-term performance in demanding environments and contribute to predictable behavior when used in precision analog circuits. Because the 2SC901 strikes an effective balance between voltage handling, current capability and frequency response, it is a versatile choice for hobbyists and professionals building small- to medium-power devices. Typical uses include audio amplifiers, preamplifier stages, oscillators, and general switching circuits where a combination of reasonable power handling, frequency response and low noise is required.
