Insulated Gate Bipolar Transistor (IGBT) was born around 1980, and its invention was much later than BJT transistor and MOSFET. In this way, this new device naturally combines the advantages of its predecessors. From the equivalent circuit diagram, IGBT is essentially a composite of a MOSFET and a BJT, and also has two characteristics: high input impedance of MOSFET and low conduction voltage drop of BJT.

A diode is an electronic device made of semiconductor materials, consisting of a PN junction, external leads, and a shell packaging, with the written symbol VD. A diode has two electrodes, the electrode led out from the P region is called the anode (positive electrode), and the electrode led out from the N region is called the cathode (negative electrode); Due to the unidirectional conductivity of the PN junction, the current direction when the diode conducts is from the anode to the cathode through the inside of the tube.
