![]() IGBT has a lower forward voltage drop compared to MOSFETĦ. IGBT has PN junctions, and MOSFETs doesn’t have them.ĥ. IGBTs are better in power handling than MOSFETSĤ. Terminals of IGBT are known as emitter, collector, and gate, whereas MOSFET is made of gate, source, and drain.ģ. Although both IGBT and MOSFET are voltage controlled devices, IGBT has a BJT like conduction characteristics.Ģ. As of 2018, over 50 billion power MOSFETs are shipped annually. As of 2010, the power MOSFET accounts for 53 of the power transistor market, ahead of the insulated-gate bipolar transistor (27), RF power amplifier (11) and bipolar junction transistor (9). IGBT modules (consists of a number of devices) can handle kilowatts of power.ġ. The power MOSFET is the most widely used power semiconductor device in the world. Therefore, it has the advantages of both high current handling capability, and ease of control. It is gate driven like MOSFET, and has current voltage characteristics like BJTs. IGBT has the combined features of both MOSFET and bipolar junction transistor (BJT). IGBT was introduced to the market in 1980s. It is a type of transistor, which can handle a higher amount of power, and has a higher switching speed making it high efficient. IGBT is a semiconductor device with three terminals known as ‘Emitter’, ‘Collector’ and ‘Gate’. Therefore, MOSFET is used in digital CMOS logic, where p- and n-channel MOSFETs are used as building blocks to minimize power consumption.Īlthough the concept of MOSFET was proposed very early (in 1925), it was practically implemented in 1959 at Bell labs. This insulation causes low power consumption, and it is an advantage in MOSFET. Gate is made of metal, and separated from source and drain using a metal oxide. ![]() Drain and source are made of n type semiconductor for n channel MOSFETs, and similarly for p channel devices. MOSFETs are available in four different types, such as n channel or p channel, with either in depletion or enhancement mode. Therefore, MOSFETs are voltage controlled devices. Here, drain current is controlled by the gate voltage. MOSFET is a type of Field Effect Transistor (FET), which is made of three terminals known as ‘Gate’, ‘Source’ and ‘Drain’. Metal Oxide Semiconductor Field Effect Transistor (MOSFET) Both devices have similar looking structures with different type of semiconductor layers. MOSFET (Metal Oxide Semiconductor Field Effect Transistor) and IGBT (Insulated Gate Bipolar Transistor) are two types of transistors, and both of them belong to the gate driven category.
