An SIT-BJT Operation Model for SITh in the Blocking State
静电感应晶闸管在阻断态时的SIT-BJT等效工作模型

A SIT-BJT model is proposed for static induction thyristors (SITh) operation in the blocking state.On the basis of the physical mechanism,this model is presented analytically in terms of governing equations that link the electrical parameters to the structural parameters.The model is verified by numerical simulation and theoretical analysis.Based on the model,the variations of the electrical parameters such as the potential barrier,the anode junction voltage drop,and the current amplification factor are studied and discussed.
