IGBTs (Insulated Gate Bipolar Transistors) are power semiconductor devices that combine the high switching speed of MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) and the low saturation voltage of bipolar junction transistors (BJTs). This makes them ideal for high-power applications, such as motor control, renewable energy systems, and power inverters.

IGBTs consist of three main components: an N-type semiconductor, a P-type semiconductor, and an insulated gate. When a voltage is applied to the gate, it creates an electric field that controls the flow of current between the N-type and P-type semiconductors. This allows for precise control of the power flow in high-power applications, and the insulation of the gate reduces the risk of electrical breakdown.

One of the biggest advantages of IGBTs is their fast switching speed, which allows them to respond quickly to changes in voltage and current. This is especially important in applications that require rapid power changes, such as motor control. The low saturation voltage of IGBTs also makes them ideal for high-power applications, as it reduces the risk of thermal damage and extends the lifespan of the device.

IGBTs can handle high voltage and current levels, making them suitable for high-power applications. They are also capable of operating at high frequencies, making them useful for applications such as high-frequency power conversion. In addition, IGBTs are highly reliable and durable, making them ideal for use in harsh industrial environments.

What are the benefits of IGBTs?

IGBTs are power semiconductor devices that combine the high switching speed of MOSFETs and the low saturation voltage of BJTs, making them ideal for high-power applications such as motor control, renewable energy systems, and power inverters. With fast switching speed, low saturation voltage, high voltage and current handling capabilities, and high reliability, IGBTs are a versatile and important component in modern power electronics.

IGBTs are traditionally used with Silicon based dies for Power modules. They are made from an emitter, collector and gate terminals, while MOSFETs consist of source, drain and gate terminals.  Just like MOSFETs, depending on whether they are thru hole or surface mount they can be housed in a multitude of packages. TO220, TO262 and TO 247 are very common for thru-hole components while TO263 (D2PAK) and TO252(DPAK) are go-to packages for surface mount.

These devices are preferred for medium to high power applications. Compared to MOSFETs they can handle high voltages due to their lower conduction loss but due to their nature they are not meant for high-frequency applications. They can be typically found in welding equipment, automotive power modules, UPS, chargers and are the leading technology in mainstream high voltage packages.
