The C945 NPN Transistor SOT-23 SMD Package is a low-noise silicon epitaxial transistor designed for general-purpose amplification and switching in compact surface-mount circuits. Its stable gain, low leakage, and fast response make it suitable for audio preamps, signal processing, driver stages, and low-current switching applications.
