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,tradeoff 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.
