The IXFB72N55Q2 is a type of field-effect transistor (FET) that belongs specifically to the class of single metal-oxide-semiconductor field-effect transistors (MOSFET). It is a type of transistor specially designed for use in a variety of applications revolving around high-frequency power amplification. In this article, we will take a closer look at its specifics and delve into the IXFB72N55Q2 application field and working principle.

Before we discuss the IXFB72N55Q2, let us first get an overview of FETs and MOSFETs in general, so we can better understand how this device works and how it functions:

A field-effect transistor is a type of transistor in which electric fields are used to control the alignment of the current flow. It consists of three layers: the emitter, the base, and the collector. The emitter is the layer conducting the current, the base is an insulator, and the collector is the layer collecting and controlling the current. There are two types of FETs: junction FETs and insulated-gate FETs, which are also referred to as MOSFETs.

MOSFETs have a gate that is insulated from the other layers, and it is through this gate that voltages are applied to change the flow of current. They also have a variety of subtypes, such as single MOSFETs, floating MOSFETs, depletion-mode MOSFETs, and enhancement-mode MOSFETs, depending on the application. The IXFB72N55Q2 falls into the category of single MOSFETs.

The IXFB72N55Q2 is specifically designed to be used in high-frequency applications. It has a Vds range of 50 to 100V and can handle up to 10A of drain current. In addition, it has an RDS (on) of 18.7mΩ, which makes it an ideal device for use in power amplifiers.It is also very power efficient, boasting a drain efficiency of up to 95%.

In terms of its working principle, the IXFB72N55Q2 is quite simple. It relies on the gate-drain voltage applied to the gate of the FET to control the mode. With a gate-drain voltage of 0V, the device is in the off state and no current can pass through it. When the gate-drain voltage is increased, the device enters a linear or saturation state, allowing current to flow from the drain to the source. As the gate-drain voltage is increased further, the device enters its cutoff state, in which no current can flow.

So, that is an overview of the IXFB72N55Q2 application field and working principle. This device is designed primarily for use in power amplifiers, due to its high power efficiency and low on-resistance ratings. Its simple working principle also makes it ideal for applications that require a high degree of precision, such as those involving high-frequency signals.
