摘要
对浮结型及超结型肖特基势垒二极管静态及动态特性进行了解析及模拟。静态特性通过解析击穿电压与导通电阻之间的关系得到。反向恢复特性通过二极管电容随反向电压变化关系解释,商用混合模拟器MEDICI模拟结果表明浮结结构具有软恢复特性,软度因子为0.949。超结结构恢复特性较硬,软度因子为0.780 7。当考虑这两种耐压结构时,必须权衡静态及动态之间的关系。
In this paper,the static and dynamic characteristics of superjunction and floating junction Schottky barrier diodes were analyzed and simulated.Work principles of the device were reported,trade-off between breakdown voltage and specific resistance was theoretically calculated and compared.The reverse recovery characteristics were analyzed by diode capacitance as function of diode reverse voltage,the mixed circuit-device simulator MEDICI shown that floating junction had softness factor 0.949,while hard recovery characteristics were obtain for superjunction structure with softness factor 0.780 7.Trade-off must be made when static and dynamic performance is considered.
