The physical effects of the carrier distribution in the channel on the dynamical performance of a static induction thyristor(SITH) have been studied numerically and experimentally. The analytical expressions of the minority carrier distribution in the channel of the SITH were also derived and the space charge distribution controlling mechanism on the current of the SITH under high level injection have been analyzed deeply. The relationships among the minority carrier distribution, potential distribution, I –V characteristics and transient performances of the SITH are revealed.
