What do you think the Best in Semiconductor Industry IGBT or Super Junction MOSFET?

In recent years, environment compatibility, energy efficiency, flexibility and cost reduction have emerged as critical global issues across the semiconductor industry. Over the years, the electronics industry has been launching various power semiconductor solutions, such as insulated gate bipolartransistors (IGBTs) and super junction MOSFETs (metal oxide fieldeffect transistor). IGBTs and super junction MOSFETs are used in switching applications in different end-user applications, including uninterrupted power supplies (UPS), wind turbines, PV inverters, rail tractions, electric vehicles and hybrid electric vehicles, and other industrial applications.

IGBT offers faster switching and higher efficiency. As a power semiconductor device, it competes against other devices and technologies such as Gallium Nitride (GaN), MOSFETs, and Silicon Carbide (SiC). IGBTs offer the features of both bipolar transistor and MOSFETs offering both high-voltage and high input impedance. IGBTs are preferred for the applications which require high breakdown voltage and high input impedance, owing to their better conductivity modulation characteristics. IGBTs are cost effective as compared to traditional MOSFETs and are replacing traditional MOSFETs in various applications. IGBTs are preferred in motor drive applications where high current and voltage are required.

Super junction MOSFETs achieve significant improvement over conventional MOSFETs by employing the principle of super junction charge-balance. Super-junction MOSFETs are manufactured with a deep-trench process technique. The demand for super junction MOSFETs is high in applications that require significantly high power ratings.
