MJE2955TG

Transistors - Bipolar (BJT) - Single

MJE2955TG is a PNP linear amplifier manufactured by STMicroelectronics. It is classed as a bipolar junction transistor (BJT). This type of transistor consists of three layers of doped silicon materials, each of a type, giving it its name of bipolar or NPN. It is an often used amplifier transistor in electronic circuits and it can control signal, voltage and current.

A MJE2955TG transistor has a wide application field and is used in low power audio amplifiers and low noise analog circuits. It is commonly used as a switch, amplifier, or as a combination of both. It is also used for linear parts in switching power supplies, as well as for signal buffering and correction.

The working principle of the MJE2955TG is quite simple. It is composed of three main parts, an emitter, base and collector. When voltage is applied in the direction of current flow, it allows current to flow from the emitter to the collector. The base acts like a gate, allowing the current to be controlled by the voltage applied to it. That voltage is called the "base voltage". Depending on the amount of current flowing, the amount of voltage transferred to the collector may be adjusted.

When the base voltage is higher than the emitter voltage, the voltage on the collector is increased. This is why it is called a "linear amplifier". The higher the current, the higher the collector voltage will be. This means that the transistor can control and amplify the current.

The MJE2955TG provides good gain in low voltage applications and is suitable for low power audio amps. It is also used to increase current and voltage levels in linear applications. The transistor is also useful for switching power supplies, as it can regulate the current with minimal power consumption.

The MJE2955TG has a fairly straightforward working principle. It is made up of a three-layered structure of doped silicon materials. When a voltage is applied in the direction of current flow, it allows current to flow from the emitter to the collector. The base acts like a gate, allowing the current to be regulated. The amount of current is determined by the amount of voltage applied to the base, which is called the "base voltage". Depending on the amount of current flowing, the transistor can control and increase the voltage and current levels.

MJE2955TG is a versatile and frequently used transistor in many applications. With its low power consumption and linear operation, it can be used for amplifying weak signals, controlling voltage and current, and switching power supplies. It is a dependable and valuable addition to any system.
