ZTX790ASTOB

Introduction

ZTX790ASTOB transistors are one of the most popular transistors available in the market. They are of the single bipolar junction transistor (BJT) type, specifically NPN polarity. These transistors feature a relatively low collector-emitter breakdown voltage and can handle up to 5A at a maximum collector current. They are mainly used in applications such as audio amplification and switching applications, where the emission gain and peak collector current capacity of the transistor are beneficial. In this article, we will discuss the typical application fields and working principles of such transistors.

Application Fields

The ZTX790ASTOB is widely used in various electronic device applications as it offers a range of features including low on-state resistance and high breakdown voltage, making it suitable for a variety of application circuits. It is mainly used for audio amplifiers and switching applications, where the relatively low collector-emitter breakdown voltage and the high peak collector current capacity of the transistor come in handy. In audio amplifiers, these transistors are used to provide high gain and wide bandwidth, allowing them to amplify a signal without introducing distortion. They are also used in switching power supplies, as they have a low on-state resistance and are able to handle relatively high currents, compared to other transistors. The ZTX790ASTOB is also used in various industrial applications, such as motor control applications and in the application of controlling heating or cooling by controlling the power output of an electric heater or air conditioner.

Working Principles

The ZTX790ASTOB is a single NPN bipolar junction transistor. It consists of three layers: an n-type layer, a p-type layer, and an n-type layer. These layers are connected together to form an NPN structure. When an electric current passes through the transistor, it controls the amount of current that can flow through the other layers. The NPN transistor works in the following manner. When a small current is allowed to flow through the base of the transistor, a larger current is allowed to flow through the collector and emitter. This current difference is caused by a phenomenon known as the junction voltage. The junction voltage is the difference between the voltages on the base and emitter of the transistor. The higher this voltage, the higher the amount of current that can flow through the transistor, and thus, the greater the gain of the transistor. The ZTX790ASTOB has a low on-state resistance and high breakdown voltage, making it ideal for use in applications that require a high current capacity, such as audio amplifiers, switching power supplies, and motor control applications.
