Working Principle of BFS20W, 115 Transistors

The working principle of BFS20W,115 transistors is based on the fact that current flowing through a semiconductor material can be controlled by the voltage applied to it (this is known as \'current gain\'). A BJT transistor consists of three terminals: the emitter, base, and collector. When a voltage is applied to the emitter-base junction, a small current is allowed to flow between the base and the collector, which is amplified in the process. The current flow is determined by the voltage applied to the base, and the current gain can be adjusted by changing the voltage applied to the base.

Conclusion

In conclusion, BFS20W,115 transistors are a type of BJT (Bipolar Junction Transistor) single that are designed to reliably and cost-effectively operate at high electrical currents and high collector voltages. They are used in a variety of applications, such as switching, amplification, low-frequency oscillators, power supplies, and logic circuits. BFS20W,115 transistors work on the principle of current gain, which allows the flow of current between base and collector to be controlled by the voltage applied to the emitter-base junction.
