A solid-state semiconductor switch


An insulated-gate bipolar transistor is a solid state switch that is used in many industrial and automotive applications, as well as home appliances. Because of the bipolar transistor structure, it can handle extremely high current current, and is tolerant to spikes and overloads.
There are multiple types of IGBTs, with on-off delay features and various features to reduce heat, improve power density and increase efficiency. Voltages range from about 300V to more than 3,000V,
