BC846AW,135 Application Field and Working Principle

BC846AW,135 is a transistor that belongs to the group of transistors known as bipolar junction transistors (BJT). It is a single-junction transistor which is used for a variety of purposes in electrical and electronic circuits. This article will discuss the applications of BC846AW,135 transistor and its working principle.

The main function of BC846AW,135 is to amplify weak electrical signals. It is also used in power supply circuits as a switch. The basic operating principle of BJT transistors is the controlled transfer of electric current between the emitter and the collector. In BC846AW,135, when a current is applied to the base, it controls the amount of electron that can flow between the emitter and collector. This enables the transistor to act as an amplifier.

BC846AW,135 transistor is used in many types of applications, such as in audio amplifiers, voltage regulators, oscillators, timers, and transducers. It is also used in RF (Radio Frequency) circuits for amplifying weak radio signals. In switching applications, BC846AW,135 can turn on and off the electric current in a circuit, thereby helping to control the current levels. Additionally, it is also used in DC to DC converter circuits and Darlington configurations.

The maximum collector current of BC846AW,135 is 100 mA, and the maximum collector dissipation is 1.15 W. The voltage range of the DC collector-emitter (B VCEO) is 45V. The transistor is available in a variety of packages such as TO-92, SOT-23, SOT-223, SOT-457, and so on.

BC846AW,135 operates in the active region of its electrical characteristics which is the most ideal region for linear amplifications. It has an amplification factor, also known as the transistor gain, usually denoted by hFE, of between 65 and 300 with a typical value of 110. In active region, the output current is proportional to the input current, and the output voltage is proportional to the input voltage.

Another important application of BC846AW,135 transistor is in the Darlington configuration which is widely used in power amplification. In this configuration two transistors are connected but with one of the transistor’s base being connected to the other transistor’s collector. This configuration provides an amplified output with a voltage gain of 1,000 or more. This is because the first transistor amplifies the input signal, and the second transistor amplifies the output from the first transistor.

The BC846AW,135 is a widely used transistor and is available in almost all electronic stores. It is a low cost and efficient transistor making it suitable for a variety of electronics applications. Its simple working principle and wide range of applications make it an ideal choice for use in both hobbyist and professional applications.
