Abstract :
A novel single gate MOS controlled current saturation thyristor (MCST) device is proposed. In the on-state the MCST operates in thyristor-like mode at low anode voltage and enters the IGBT-like mode automatically with increasing anode voltage, offering a low on-state voltage drop and current saturation capability. The saturation current density of the MCST is strongly dependent on the on-set voltage or the p+ buffer/n-well junction, leading to its excellent safe operation area (SOA) and making it suitable for high power applications
