FJX3904TF Discrete Semiconductor Products

The FJX3904TF is a Bipolar Junction Transistor (BJT), a type of single-junction transistor which is composed of two p-n junctions joined together. FJX3904TF is a high-current DC power transistor consisting of two N-type and one P-type layers. BJT transistors are used for controlling and switching of electric current through electrical circuits. They are used in a variety of applications, from simple circuits for amplifying signals to complex switching and high-frequency circuits such as radios.

FJX3904TF has a wide range of application, primarily as a power switching device, such as power supplies, motors, lighting, and power amplifiers. Additionally, FJX3904TF can also be used in audio systems, radio receivers, audio amplifiers, and other high-frequency applications. It can also be used in RF amplifiers and other RF applications. The FJX3904TF is capable of delivering high current, up to 50 Amps, making it ideal for high power applications.

Working Principle

FJX3904TF consists of three basic elements, namely the base, the collector, and the emitter. When a voltage is applied to the base-emitter junction, it allows a current to flow from the base to the emitter. The current flow then allows more power to the collector which then amplifies the current to the desired level.

The characteristics of FJX3904TF transistors depend on the voltage between the base, collector, and emitter. By changing this voltage, the current gain, or “hfe”, of the device can be changed as well. This allows FJX3904TF to be used in a variety of different applications.

Current Gain

The current gain, or hfe, is the ratio of collector current to base current, and is an important figure to consider when selecting a transistor for any application. FJX3904TF has a very high current gain of up to 2500, which makes it suitable for applications that require large amounts of power. It is capable of delivering up to 50 Amps of current.

In addition to the current gain, FJX3904TF offers a wide range of other benefits, such as low power dissipation and low noise levels. It is capable of delivering power efficiently and reliably, and is highly suitable for a variety of different applications.

Summary

The FJX3904TF is a single-junction bipolar junction transistor (BJT) which can be used for a wide range of applications. Its high current gain and power efficiency make it ideal for high current applications, such as power supplies, motors, and lighting. By changing the voltage between the base, collector, and emitter, the current gain, or hfe, of the device can be adjusted, allowing it to be used for different applications. Overall, FJX3904TF is an excellent choice for a wide range of applications.
