Abstract :
Field controlled thyristors (FCTh) have been realized by a recessed gate technique. Static and dynamic characteristics are measured and compared to theoretical results. During turn-off a new latching mechanism is observed which is explained in terms of a comprehensive physical model. New advanced cascode and cascade circuits are proposed with reduced on resistance, very high current gain and fast, snubberless switching.
