About 2SC1815 NPN Transistor
The 2SC1815 is a silicon NPN transistor manufactured using the epitaxial planar process, designed for general-purpose applications. It is widely used in audio-frequency amplifiers and driver stages due to its high DC current gain (hFE) and excellent linearity. With a collector-emitter voltage (VCEO) of 50V and a collector current (Ic) of 150mA, this transistor is suitable for low-power switching and amplification tasks in consumer electronics, industrial controls, and hobbyist projects. Its TO-92 package ensures easy mounting on breadboards and PCBs. Choose the 2SC1815 for reliable performance, cost-effectiveness, and compatibility with a wide range of circuits. It is a direct equivalent to the C1815 transistor and is available from reputable manufacturers like Central Semiconductor and Toshiba.
