| Abstract: | Based on the model of thyristor short circuit emitter, a novel multi cell structure model for silicon surge protection device is proposed in this paper. The break over characteristics and the holding current of this model are analyzed in detail. Under the normalization condition, the quantitative analysis for their compromise determines an optimized value of D/d under certain process condition. This analysis has the significance for increasing the surge handling capability of SSPD, improving the response characteristics and realizing this device for production in scale. |
