Thyristors provide surge protection in high exposure environments

LITTELFUSE Pxxx0MEL 5kA Series and Pxxx0FNL 3kA Series SIDACtor protection thyristors are optimized to protect equipment located in high exposure environments from severe overvoltage transients. Devices provide enhanced reliability through multiple high energy surge events. Unlike many non-semiconductor-based high power protective products, which can experience functional degradation after only a few surge events, the semiconductor-based components will continue to provide protection through multiple surge events without functional degradation.
