Introduction to IGBT and Its Use in Electronic Circuits

IGBT stands for Insulate gate bipolar junction transistor. It is a three terminal device which is used in a large number of electrical applications. The IGBT combines features from the
MOSFET and the BJT that is useful in practical switching applications that employ high-voltage and high-current switching.

Terminals of IGBT

The IGBT has three terminals:

  1. Collector
  2. Gate
  3. Emitter



IGBT’s are advanced to BJT because they have fast switching speed as compared to BJT’s. In many switching speed applications, they are used instead of BJTs.


In terms of collector-to-emitter current handling, the IGBTs are superior to MOSFET.
The video below demonstrates the basic concepts you need to know about IGBT.
