IXGQ20N120B Application Field and Working Principle

IXGQ20N120B is an electronic component commonly referred to as Insulated Gate Bipolar Transistor (IGBT). IGBTs are widely used in various industrial applications, and IXGQ20N120B is such a component, specifically designed for medium to high current applications with switching and instant off capabilities.

IGBTs, like MOSFETs, are voltage controlled, but are simpler to operate due to their higher range of input voltages, which is the reason they are used in industrial applications. Their main advantages are low power, high efficiency and high switching frequency.

Working Principle of IXGQ20N120B

IXGQ20N120B works on similar principles as MOSFET, but the operational differences arise due to the architecture. The basic device architecture consists of three terminal regions; gate, source and drain. It relies on the combined action of two oppositely charged regions, one formed from the Drain terminal and the other from the Gate terminal.

It works on the principle of minority carriers, i.e. electrons or holes which are generated from the Base terminal and pass through the Collector regions. The Gate terminal helps to control the flow of these carriers. When the Gate terminal is given a negative voltage, it acts as a barrier and prevents the carriers from passing through the Collector regions. This helps in operating the device as only requisite current passes through the device. Similarly, when the Gate terminal is given a positive voltage, it allows the carriers to pass through. This helps in controlling the current flow through the device, thus controlling the device.

Application Field of IXGQ20N120B

IXGQ20N120B is mainly used in medium to high current applications. These applications include applications like motor control, power switching, and switching power supplies. It is also used in products where high frequency and high current are required like welding machines, induction heating, and flyback transformer applications.

It is also used in applications where peak power and instant off capabilities are required. Some of the applications of IXGQ20N120B are in Inverters, Uninterruptible Power Supplies (UPS), solid state relays, rectifiers, power supplies, and LED lights.

In addition, IXGQ20N120B is also used in many consumer electronic components. For example, it is used in drivers for AC/DC circuits, drivers for solid state lights, and in variable-frequency drives for motor control.

IXGQ20N120B is also used in automotive applications such as in engine start/stop systems and in HVAC controllers.
