P-channel IGBT shares a similar structure to the N-channel IGBT except the doping is reversed in each layer.
The P+ layer at the bottom is the drain or the collector. The n+ layer at the top of the IGBT is the source or the emitter. The other two layers are called the body region (J 2) and the drift (J 1). The injection layer is very integral to the characteristics of the IGBT. The only difference is that the injection layer is p + and not n + substrate as in Power MOSFET. They are highly efficient and fast switching, plus they have high current and low saturation voltage characteristics.What is a typical application of IGBTs?IGBTs are widely used in electronic applications, including: consumer electronics, industrial technology, transportation and electric motors, aerospace electronic devices, and applications within the energy sector.IGBT is made of silicon and is very similar in structure to Power MOSFET. IGBT transistors are a cross between bipolar junction transistors (BJTs) and MOSFETs. However, MOSFETs are characterised by a lower forward voltage at lower current densities due to the absence of diode Vf in the IGBT's output BJT.An IGBT transistor module (insulated-gate bipolar transistor) consists of one or more IGBTs and is used in many types of industrial equipment due to its reliability.
The type of IGBT transistor you choose will vary depending on the exact power level and the applications being considered, and so it is important to know as many of your exact requirements as possible to choose the correct IGBT for your application.What is a difference between MOSFETs and IGBTs?An IGBT has a much lower forward voltage drop compared to a conventional MOSFET in higher blocking voltage rated devices. They are controlled by a metal oxide semiconductor gate structure and are widely used for switching electrical power in applications, such as welding, electric cars, air conditioners, trains, and uninterruptible power supplies.What are the different types of IGBT Transistors?There are various types of IGBT transistors and they are categorised by different parameters, such as maximum voltage, collector current, packaging type, and switching speed. You can find out more in our guide to IGBTs.How do IGBT transistors work?IGBT transistors are three-terminal devices which apply a voltage to a semiconductor, changing its properties to block power flow when it's in the off state and allow power flow in the on state. RS have a curated range of IGBTs from a multitude of trusted brands, including Infineon, ON Semiconductor, STMicroelectronics, and many more. They have many benefits as a result of being a cross between two of the most common transistors: Bipolar transistors and MOSFET. IGBTs IGBT (insulated-gate bipolar transistors) are semiconductors mainly used as switching devices to allow or stop power flow.
