正向浪涌电流是最大额定值之一,代表正向瞬时电流。其主要用于二极管。非重复最大允许峰值电流是在指定结温下允许一个周期的50Hz正弦波形(导通角180度)正向流动的电流值。在产品数据表中,该值表示为非重复峰值正向浪涌电流(IFSM)。根据不同产品,采用浪涌特性曲线从1个周期到50个周期的浪涌电流。
在东芝的碳化硅(SiC)肖特基势垒二极管(SBD)中,此结构已经过优化。其浪涌电流大于硅(Si)SBD,是直流额定电流IF(DC)的7至9倍
绝对最大额定值(注)(除非另有说明,Ta=25℃)
备注:即使工作条件(即工作温度/电流/电压等)在绝对最大额定值范围内,在重负载(例如,应用高温/大电流/高电压以及温度显著变化等条件)下连续使用可能会导致本产品的可靠性显著下降)。
请参考《东芝半导体可靠性手册》(“操作注意事项”和“降额概念和方法”)以及单独的可靠性资料(即可靠性测试报告、估计故障率等),设计合理的可靠性。
