Bipolar transistors which are also popularly known as bipolar junction transistors (BJTs) are active and passive components in the electronics circuit employed either as switches or amplifiers. Jeking realizes how vital bipolar transistors are for numerous electronic systems, and therefore comes up with a large portfolio of good quality bipolar transistors that suit the harsh needs of the electronics world. Our products are adherence to urban practice and are interchangeable in various circuit layouts.
Working of Bipolar transistors
Bipolar transistors function with the movement of charge carriers (electrons and holes) through the base-emitter and base-collector junctions. The transistor can be made to increase the amount of signal present at the collector or make a switch current through or not by varying the amount of current entering into the base of the transistor.
Important Properties of Bipolar Transistors
Current Gain: The beta (β) current gain sometimes referred to as current amplification of a bipolar transistor is the factor of the ratio of the collector current over the base current that is almost assumed to be nonexistent in most sophisticated practical circuits. This is an important determinant of the amplification ability of the transistor.
Saturation: The state of the transistor is sometimes referred to as saturation whenever the collector-emitter voltage is low. It's this state that is very useful in switching applications.
Breakdown Voltage: The breakdown voltage is the level of voltage that the collector and emitter can withstand without the transistor failing.
Frequency Response: Bipolar transistors have a frequency response range that dictates the area where these devices can be used discretely. The cut off frequency is the frequency below which there is no gain from the transistor.
Applications of Bipolar Transistors
Bipolar transistors have been used in a variety of electronic devices, such as amplifiers, oscillators, and digital circuits, logical or otherwise In addition, they are utilized in electronics including power control, and signal processing.
Bipolar transistors are very important in an electronic circuit since they feature flexibility and reliability in amplification as well as switching. By knowing the properties of the devices, one can determine how best to use them in several electronic devices. There is a determination from Jeking to help the electronics fraternity by providing the required components and tools that will enable safe use of bipolar transistors.
