2SC1573BR is a bipolar transistor with NPN structure, which is classified as a single transistor. This kind of transistor has a wide application field and is commonly used in signal amplification and active matching circuits. This article will explain the application field and working principle of 2SC1573BR.

Application field:

2SC1573BR transistors have broad applications, some of which include high-frequency output stages in wireless communication systems, power switching circuits for electronic motors and toys, such as toy cars and airplanes. Apart from that, 2SC1573BR also is popularly seen in amplifiers, oscillators, signal converters, interface and logic circuits, etc. Thus, these transistors are adaptable in many fields, resolving numerous problems.

Working principle:

2SC1573BR works based on the principles of the bipolar junction transistors. As the most important parameter of transistors, the current gains alpha will always remain as the same value of the current flowing through the base region Ib. Its working process can be broken down into three steps. Firstly, when there is a small ac signal across base and emitter, base-to-collector current Ib-C will expand due to the relatively larger current amplification factor alpha. This current Ib-C is greatly increased compared to the input current Ib-E. Finally, the current from collector to emitter will be determined by the sum of these two currents Ib-C and Ib-E. In the second step, the voltage between collector and emitter will also be reversed and thus increases the output current Ic-E that can be further amplified or used to directly drive load. In the third step, the current amplification factor alpha drops as the changing base-emitter voltage is amplified. This reduces the current Ib-C and stabilizes the original configuration of the emitter and collector junction. This is how 2SC1573BR transistors perform their tasks in the amplification and conversion of signals.

Conclusion:

To conclude, 2SC1573BR transistors are commonly used in many application fields and its working process is based on the principles of the bipolar junction transistors. With a relatively larger current amplification factor alpha, these transistors can amplify signals and serve as switching circuits in many wireless and electronic equipment.
