FMB3906 Discrete Semiconductor Products

The FMB3906 is a biased NPN Silicon array transistor, designed for power circuits and general purpose amplifiers. This type of array transistor is able to provide tremendous savings in the fabrication process of linear integrated circuits, mainly due to the fact that they include multiple transistors in the same package. In addition, they can be operated in several different configurations, with the biasing of each stage being easily adjustable, so they can be used in almost any kind of application.

The FMB3906 array transistor includes two NPN transistor stages, each one with a grounded emitter and a shared base as its input. The two stages are connected in parallel, with the second stage having a slightly larger collector-emitter voltage rating than the first one. Each stage also includes its own biasing resistors, which are adjustable in order to match the optimal current and voltage settings of the application.

The main advantage of the FMB3906 array transistor is the fact that it can be used for a wide range of amplifier applications. It can be used as a preamplifier, with the first stage providing the necessary gain, and the second stage being used as an output buffer. It can also be used in power amps, since the biasing resistors can be adjusted to suit the power requirements of the application. Additionally, the FMB3906 can be used as a driver stage in small signal amplifiers, as it can provide a high current output.

The working principle of the FMB3906 array transistor is relatively simple. In each stage, the NPN transistors act as current amplifiers, with the current flowing through the transistors being proportional to the input voltage. The biasing resistors act as voltage dividers, setting the voltage at the base of the transistors, and thus controlling the amount of current flowing through them. This, in turn, controls the output voltage of the transistor, and thus the strength of its amplification.

In conclusion, the FMB3906 array transistor is a great option for a range of applications. Its simple yet highly functional design makes it perfect for use as a preamplifier, power amplifier, or driver stage. Its highly adjustable biasing resistors provide plenty of flexibility in terms of the current and voltage settings, allowing it to be used in a range of different applications. This makes it an extremely versatile device, and it is a great choice for any designer looking to maximize the efficiency and cost effectiveness of their linear integrated circuits.
