Transistors - Bipolar (BJT) - Single

The BC857AW,135 is a single bipolar junction transistor (BJT). It falls within the category of transistors that have three pins.The transistor is used as an amplifier or switch to either turn current on or off in electronic devices. It operates by controlling the current between Collector (C) and Emitter (E) using the Base (B).

Principle of Operation

The three pins of the transistor are known as the collector, base and emitter. The BJT works on the principal of current amplification. A small current entering into the base of the transistor is amplified and used to control a larger current flow between the collector and emitter. The current entering the base is known as the input current and the current flowing between the collector and emitter is known as the output current.

The size of the output current is regulated by the size of the input current. When a small amount of current flows into the base of the transistor, the collector-emitter current flow is unaffected; however, when a relatively large amount of current is sent into the base of the transistor, the collector-emitter current flow is amplified in proportion to this larger current. This amplification allows for a wide range of current control between the collector and the emitter.

Fields of Application

The BC857AW,135 has a variety of uses. It can be used as an amplifier in high frequency applications, such as radio circuits. It can also be used as an amplifier or switch in micro-controller circuits, as well as in logic circuits and digital circuits. The BC857AW,135 is also useful in power switching applications, being able to carry current up to 500 mA.

Additionally, the BC857AW,135 is commonly used in computer peripheral devices such as keyboards, mice, joysticks, and printers. It is also used in audio amplifiers and video amplifiers. It is commonly used in consumer electronic devices such as TVs, VCRs, and DVD players as a switch or amplifier.

Conclusion

The BC857AW,135 is a single bipolar junction transistor (BJT) that is able to control the current between the collector and emitter using the base. It can be used as an amplifier or switch in various devices. It operates on the principle of current amplification, with a small current entering into the base of the transistor being amplified and used to control a larger current flow between the collector and emitter. The BC857AW,135 has a variety of applications, including high frequency applications, logic circuits, digital circuits, power switching, computer peripheral devices, audio amplifiers and video amplifiers, and consumer electronics.
