September 13, 2016 // By Julien Happich
Designed to protect low-data-rate interfaces and outdoor data interfaces in general industrial applications, the Pxxx0S3NLRP series of SIDACtor protection thyristors from Littelfuse come in DO-214AB (surface-mount) packages.

It provides robust surge protection performance at up to 2.5kA, while maintaining much lower switching threshold (VS) and on-state voltage (VT) than traditional protection solutions like Gas Discharge Tube (GDT) technology. The devices also offer crowbarring power fault protection superior to typical clamping devices. Component properties do not degrade after multiple surge events within the rated limits, extending equipment lifetime. The devices are certified, environmentally friendly and suitable for worldwide usage, to help line drivers comply with global standards.
