Among the power semiconductor devices in the transistor field, in addition to IGBTs there are MOSFETs and bipolar types primarily used as semiconductor switches. With respect to switching speed, bipolar types are suitable for medium-speed while MOSFETs support the high-frequency range. The RGWxxTS65x series of IGBTs supports 650 V operation and features the lowest VCE_(SAT) that results in the lowest switching losses.
