The typical symbol of IGBT along with its image is shown below.Īs mentioned earlier an IGBT is a fusion between a BJT and MOSFET. These devices are mostly used in amplifiers for switching/processing complex wave patters with pulse width modulation (PWM). It is a three-terminal semiconductor switching device that can be used for fast switching with high efficiency in many types of electronic devices. IGBT is the short form of Insulated Gate Bipolar Transistor. In this article, we get familiar with the basics of IGBT, how they work, and how to use them in your circuit designs. You can think of IGBT as a fusion between BJT and MOSFET, these components have the input characteristics of a BJT and output characteristics of a MOSFET. So, we moved another popular power electronic switching device called the IGBT. But, both these components had some limitations to be used in very high current applications. We have already discussed in detail about the working of BJT and the working of MOSFET and how they are used in circuits. Symbol fixes (p-types) according to defines in IEC EN 60617-5.The most popular and commonly used power electronic switch devices are the Bipolar Junction Transistor BJT and the MOSFET.
