IGBTs, or Insulated-Gate Bipolar Transistors, are discrete three-terminal semiconductors primarily designed to function as switching devices to allow or stop power flow in various electronic devices. They are robust devices that offer various benefits as they are the fusion of the most common MOSFET and bipolar transistors. These devices are widely used in environments where controlled and medium-speed switching is required. In addition, they are also more economical than comparable silicon MOSFETs.
Why use IGBTs? What benefits do they offer?
Insulated gate bipolar transistors feature excellent attributes with uncountable benefits, such as:
- Feature low on-resistance
- High voltage capacity
- Fast switching speed
- Low switching loss
- Superior current conductive capability
- Low on-stage power dissipation
- Feature forward and reverse blocking attributes
- Voltage control device
- They are easy to turn ON and OFF
- Feature higher switching frequency than the BJT.
Parameters based on the Types of IGBT Transistors:
The various types of IGBT transistors are classified into various categories based on the following parameters:
- Collector voltage
- Maximum voltage
- Switching speed
- Packaging type
Key considerations for choosing the exact IGBT type:
There is a multitude of crucial requirements to consider the exact IGBT type for specific applications. However, the precise power level with particular applications is crucial before choosing your desired IGBT.
Difference between IGBTs and MOSFETs:
In blocking higher voltage rated devices, an IGBT overrides the traditional MOSFET and features a much reduced forward voltage drop. An insulated gate bipolar transistor is more reliable, particularly in industrial applications. Furthermore, they are highly robust and fast and feature high and low saturation voltage attributes compared to MOSFETs.
What are the uses of IGBTs?
IGBTs are the typical components of a wide variety of electronic devices and are used in applications such as:
- Consumer electronics
- Transportation
- Industrial technology
- Aerospace electronic devices
