BCX799_D26Z application field and working principle

The BCX799_D26Z is a general-purpose, bipolar NPN transistor designed for communication systems and other high-frequency applications. This bipolar NPN transistor is offered in a plastic 2-pins (Dip-26) package and can be used in a wide range of applications from low current, high speed switching to high current, low-frequency amplifier design. It is an ideal solution for applications such as pre-amplifiers, headphone amplifiers, residential telephone base station amplifiers, video amplifier circuits, DC-DC converters, RF power amplifiers, and other linear applications.

Working principle

The BCX799_D26Z functions as a three-layer semiconductor device, with two p-type layers surrounding an n-type layer. In normal operation, the base-emitter junction is forward-biased and the collector-base junction is reverse-biased. When a current flows into the base of the transistor, it is amplified and flows into the collector and out of the emitter. This amplification is what enables the transistor to function as an amplifier.

The transistor is a current-controlled device, meaning that the amount of current passing through the device is controlled by the amount of current entering its base. Therefore, by increasing or decreasing the amount of current entering the base, it is possible to control the current flowing through the device at any given time. This property makes the BCX799_D26Z an excellent choice for designing circuits that require precise control of output.
