C1815 Datasheet. Specs and Replacement

The C1815 is a low-noise NPN bipolar junction transistor widely used in audio, signal amplification, general-purpose switching. It features a typical collector current of 150mA and a high DC current gain that supports stable small-signal amplification. With low collector-emitter saturation voltage and minimal noise characteristics, it performs well in preamplifiers and radio circuits. The C1815's compact SOT23 package and reliable frequency response make it a common choice for hobbyists and consumer electronics.
