UNR911MJ0L Discrete Semiconductor Products

The UNR911MJ0L is a pre-biased single transistor of the bipolar junction type (BJT). Bipolar transistors generally consist of two PN junctions shaped to form a three-terminal semiconductor device. They are one of the oldest and most widely used types of transistor. This model is ideal for a wide range of applications, such as amplifiers, switching, multiplexers, and interfaces.

Application Field

The UNR911MJ0L is used for general-purpose switching and amplifying applications. It can be used to drive a large current from a low-power source, making it an ideal choice for power applications. It is also suitable for use in radio-frequency circuits and computer-control circuits, as well as for audio frequency applications. The device can be operated in any of the three possible polarities, with its input and output voltages either positive or negative.

Working Principle

A bipolar junction transistor (BJT) works by using the flow of electrons between two PN junctions. By applying voltage to the Collector-Base (CB) junction, electrons can be made to flow from the Collector to the Base of the transistor. This flow of electrons can be used to either switch an electrical circuit on or off, or to amplify a signal.

BJTs also have voltage gain, meaning that they can be used to increase the voltage of an input signal above the applied DC voltage. The amount of voltage gain depends on the configuration of the circuit and the current supplied by the base.

The UNR911MJ0L has a maximum power dissipation of 2.5W, a maximum junction temperature of 150°C, and a transistor type of NPN. It is also very reliable, making it a great choice for use in applications that require stability.

Conclusion

In summary, the UNR911MJ0L single pre-biased transistor is an ideal choice for a wide range of applications, such as amplifiers, switches, multiplexers and interfaces. Its NPN transistor configuration and excellent reliability make it an excellent choice for increasing voltage of an input signal or driving a large current from a low-power source.
