SIDACtor 3 kA or 5 kA Surge Protection Thyristors

Littelfuse's Pxxx0MEL series 5 kA and Pxxx0FNL series 3 kA SIDACtor protection thyristors protect equipment located in high exposure environments from severe overvoltage transients and continue to provide protection through multiple surge events without functional degradation. Both series can be used in series with clamping devices such as varistors or TVS diodes for protecting AC power input lines.
