What is BC108 transistor?
transistors perform two primary functions. They amplify electronic signals and act as switches. The BC108 transistor is a general transistor made of silicon. The letter code "B" represents a silicon and code "C" represents the audio frequency of low power. The numbers identify a specific transistor model.
During production, pure silicon used to produce transistors is doped with other elements to change the neutral silicon property to positive and negative material. Positively doped material is marked as "P" and the negatively doped material is marked as "N." Thus, the NPN transistor has two negative layers and one positive layer. On the contrary, the PNP transistor has two positive layers and one negative layer. Transistor BC108 is a transistor NPN. In two main types of transistors, the base is made either of positive or negative material. The NPN BC108 transistor has a positive mature base and collector and the emitter are negative materials. The opposite applies to PNP transistor.
The transistor scheme shows the transistor base as a straight line with lead perpendicular to it in the center. The scheme shows the collector as a line connected to the base at an angle. The emitter is marked with an arrow facing a PNP transistor base and from the NPN transistor base. Some transistor schemes inserted the circle around the symbol.
The use of the current on the BC108 transistor base causes the current to flow through the base and out the emitter. The current emiter current allows the current to flow from the collector via the emitter. Both currents are added together and the result is amplification of the current applied to the collector. This way the transistor as the BC108 amplifies the signal.
The current cannot flow from the TS customers unless the current emiter current is present. Switching applications use this BC108 transistor characteristic to control current flow. Transistors that can quickly turn on and off and turn off are for this applicationmore appropriate than those that amplify the signals.
The characteristics of the BC108 transistor make it a transistor of the general purpose with some properties suitable for amplification of low power supply at the audio range. The overall performance capacity is limited to 300 million in the standard version and can handle up to 600 million BC108C. The audio range limit indicates that it is best suited for applications that limit frequencies to 20 Hertz to 20,000 Hertz.
with a total power limited to 300 million, the BC108 transistor is not suitable for use as a main amplifier in a house or automotive stereo. Rather, it is more suitable for low -energy, uncritical switching or for increasing signal strength for processing by another circuit. Other transistors are more suitable for high -speed switching or high forces reinforcement.
