SIDACtor® Protection Thyristors

Littelfuse SIDACtor® Protection Thyristors are thyristor devices used to protect sensitive circuits from electrical disturbances caused by lightning-induced surges, inductive-coupled spikes, and AC power fault conditions. The unique structure and characteristics of the thyristor are used to create an overvoltage protection device with precise and repeatable turn-on characteristics with low voltage overshoot and high surge current capabilities. SIDACtor components are solid state crowbar devices with a patented ion implant technology that ensures effective protection within nanoseconds. Littelfuse SIDACtor Protection Thyristors include a wide range of semiconductor protection thyristor over-voltage transient suppression devices designed to serve requirements of telecom and data networking equipment applications.
