Littelfuse Pxxx1DF-1/Pxxx1DF-1E SIDACtor®晶闸管

Littelfuse Pxxx1DF-1和Pxxx1DF-1E SIDACtor®保护晶闸管为MS-012封装、固定电压单端口系列装置,设计用于保护敏感的SLIC(用户线路接口电路)免受过电压瞬变的破坏。Littelfuse PxxxDF-1E晶闸管为增强型装置,具有针对正电压浪涌的集成快速开关二极管的特点。Pxxx1DF-1和PxxxDF-1E系列针对负电压浪涌均采用了固定电压切换装置,从而提供单端口保护。正浪涌通过增强开关二极管流向接地参考。这些Littelfuse晶闸管与工业标准可编程SO-8 SLIC保护器引脚到引脚地兼容。
