Insulated gate bipolar transistor (IGBT) and super junction MOSFET are important power semiconductor devices that are commonly used in industrial motor controls, renewable energy conversion systems, electric vehicles, and power supplies. IGBTs have high input impedance and fast switching speeds similar to MOSFETs, but with the high current and low saturation voltage capabilities of BJTs. Whereas super junction MOSFETs have higher voltage blocking capability and switching speeds compared to IGBTs due to their unique charge compensation structure. Both IGBTs and super junction MOSFETs are displacing conventional bipolar transistors in many high-power applications due to their advantages of higher efficiencies, compact sizes, and lower costs.
Market Dynamics:
The global IGBT and super junction MOSFET market growth is driven by the rising demand for energy efficient and compact power electronics devices across various industries.
