Abstract :
The characteristics of a novel 500-V, 200-A bipolar-mode SIT (static induction transistor) are reported. The sustaining voltage is the key aspect of the voltage capability under an inductive load switching; it can be improved without affecting the current gain or the switching speed. Reduction of the gate resistance is effective in raising the sustaining voltage. The current gain is improved by reducing the source aperture size. Double-layer metallization is adopted to increase effective area. An extremely low saturation voltage of 0.4 V and high current gain and high switching speed are achieved. The power loss of the SIT is 20% to 40% less than that of the IGBT (insulated-gate bipolar transistor) under 15-kHz switching
