The IXTQ86N20T is a strong enhancement mode, n-channel Field-Effect Transistor (FET) designed to withstand high voltage and power, making it ideal for a wide range of applications. It is a metal-oxide semiconductor field-effect transistor (MOSFET) with a single gate structure and applications including power amplifiers, load switches, motor control, and voltage regulators. The main advantages of this type of transistor are a low ON-resistance, high immunity to noise, low gate charge, and low gate input capacitance. In this article, we will discuss the application fields of the IXTQ86N20T and its working principle.

Applications:

The IXTQ86N20T transistor is suitable for use in a wide range of applications, including power amplifiers, load switches, motor control, and voltage regulators. It is especially useful for demanding applications due to its high maximum drain-source voltage (VDSS) of 20V and current-handling capability of 25A. Its ability to withstand a high voltage and power makes it ideal for high-power circuits, such as in audio amplifiers, switching power supplies, and automotive power systems. In addition, the transistor’s low ON-resistance and low gate input capacitance make it suitable for high-frequency switching applications, such as Pulse width Modulation (PWM) converters and motor controls.

Working Principle:

The IXTQ86N20T is a type of field-effect transistor, which operates on the principle of voltage control. A transverse electric field is created in the transistor’s semiconductor channel when a voltage is applied to the gate terminal. This electric field alters the conductivity of the channel by adjusting its resistance to current flow. The amount of current that can flow through the transistor, i.e. the ‘drain current’, is determined by the voltage applied to the gate, thus making it is possible for the IXTQ86N20T to operate as an electric switch.

When a voltage is applied to the gate terminal of the IXTQ86N20T, an electric field is created in the channel, which modulates the conductivity of the channel. If the voltage at the gate is zero, no electric field is generated and no current will flow through the channel. If a positive voltage is applied, the electric field generated in the channel increases with the applied voltage, and a certain amount of current starts to flow through the channel. The drain current increases with the gate voltage, until a ‘saturation’ point is reached.

At the saturation point, the current becomes independent of the gate voltage and the IXTQ86N20T appears to be turned off. The voltage applied to the gate terminal sets an upper limit to the drain current, and can be used to control the drain current in a precise manner. The current limiting feature of the IXTQ86N20T is especially useful in applications such as motor control, where a precise amount of current must be supplied to the motor in order to generate the necessary torque without overheating the motor.

In conclusion, the IXTQ86N20T is a versatile transistor with numerous application fields and a precise current-limiting feature. Its high maximum drain-source voltage and current handling capabilities make it suitable for demanding applications, such as high-power circuits, pulse width modulation converters, and motor control. This transistor also offers a low ON-resistance and low gate input capacitance, which makes it suitable for high-frequency switching applications, such as PWM converters and motor controls. Furthermore, the IXTQ86N20T operates on the principle of voltage control, allowing it to be used as an electric switch.
