Working Principle of 2N6488 Transistor

The 2N6488 operates as a typical NPN bipolar junction transistor, where a small current at the base controls a much larger current flowing from the collector to the emitter. When base current is applied, the transistor enters forward-active mode, allowing high-current conduction, which makes it suitable for switching applications. In saturation mode, it acts like a closed switch with very low voltage drop, improving power efficiency. In linear mode, the 2N6488 is capable of delivering smooth amplification, making it useful in audio stages and regulated power output circuits.
