The FZT795ATC is a type of bipolar junction transistor (BJT). This device is an NPN device, meaning that it utilizes two p-type semiconductor materials on the outside separated by one n-type semiconductor material towards the inside. This device is also used for single-stage amplifiers, as well as for switching applications. In this article, we will discuss the applications and working principles of the FZT795ATC transistor.

Application Field

The FZT795ATC transistor is primarily used in both linear and digital amplification. This device is commonly found in everyday electronic devices such as speakers, amplifiers, and other audio equipment. Additionally, FZT795ATC transistors are also used in industrial settings, such as controlling motor speeds, powering solenoids, and in relays. This device is also capable of switching loads with very low on-resistance and is thus capable of providing high-performance for fast switching systems.

Working Principle

The FZT795ATC transistor works by using the current from the base terminal to control the flow of the current from the collector to the emitter. This process is called current amplification, for as the current from the base of the transistor increases, so does the current flowing from the collector to the emitter. This type of device also has a voltage amplification characteristic, such that as the voltage from the base terminal is increased, the voltage from the collector to the emitter is increased as well.

The FZT795ATC transistor also utilizes a base-emitter junction that works as a diode, which helps to reduce the amount of “leakage” current that would otherwise flow through the transistor when the base node is set to a low voltage. This diode also serves to reduce “Breakdown Voltage”, which is the amount of voltage that can be applied to the base-emitter junction of the transistor before it permanently shuts off.

The FZT795ATC transistor also has a “Beta” value, which is a measure of its amplification capabilities. Beta is calculated by the ratio of the collector current to the base current. The higher the Beta of the transistor, the more current can be controlled by the base terminal. A device with a Beta of 200, for example, can control up to 200 times more current than the current that is fed into the base.

Finally, the FZT795ATC transistor also utilizes its base-collector junction as a diode, to ensure that the voltage applied to the base of the transistor is not exceeded. This mechanism also prevents the transistor from becoming permanently damaged due to over-voltage or over-current.

Conclusion

The FZT795ATC transistor is a useful device for a variety of applications, both in consumer and industrial settings. Its ability to control current via the base terminal, and to amplify voltages, makes it useful for amplification and switching applications. Furthermore, its base-emitter and base-collector junctions act as diodes, protecting it from over-voltage, and over-current.
