Working Principle of 2SB815-7-TB-E
2SB815-7-TB-E is a bipolar junction transistor (BJT) with three diodes that are connected in a circuit. It functions as an amplifier with two parts, namely an input and an output. The input serves as a voltage amplifier while the output serves as a current amplifier. The device consists of two transistors with one base and two emitters, which are connected in a Darlington configuration.
The device works by the flow of electrons in between the input and the output. When there is an input voltage applied to the base, the electrons start to move to the emitter and then to the collector. This flow of electrons increases the current flow in the collector. This increase in current will then be transferred to the output as amplified voltage. This amplified voltage is then used for various applications.
The current gain of 2SB815-7-TB-E is very high and it can amplify a very small current from the base and transfer it to the collector. The speed of the device is also very high, making it suitable for applications like high current amplifications and switching. In addition, the low noise of the device makes it suitable for use in audio amplifications.
Conclusion
To conclude, 2SB815-7-TB-E is a PNP Darlington transistor that is used in various electronics projects. The device is suitable for applications like audio amplifications, signal amplification, line drivers and power supply circuit switching. It is designed with a wide base-emitter voltage of up to 12V, which enables it to handle large signal levels and low noise with total harmonic distortion of at most 0.1%. It has a very high current gain and can amplify very small current from the base. With its wide application field and working principle, it has become a popular choice for many electronics projects.
