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.

High Exposure Surge SIDACtor Protection Thyristors

Littelfuse High Exposure Surge SIDACtor Protection Thyristors are very robust solid-state protection devices intended for use in high-exposure environments. The family includes products specifically designed for primary protection, such as cell and TO-220 devices. The High Surge Current components also feature devices capable of meeting 5kA 8/20µs for use in extreme conditions. For enhanced secondary protection requirements, a D-rated device capable of 1000A 2/10µs is available in a DO-214 package. The Littelfuse High Surge Current Protection family provides an overvoltage protection solution that helps applications comply with Telcordia GR-1089 Issue 4, and ITU-T recommendations K.20, K.21, K.44, and K.45.

P-3ACL Balanced SIDACtor® Protection Thyristors

Littelfuse P-3ACL SIDACtor® Primary Protection Balanced Thyristors feature a modified TO-220 package and are designed for use in primary protection applications. The components provide a single port overvoltage solution that enables applications to comply with the balance requirements of GR-974 and GTS-8700. P-3ACL thyristors offer high current protection as they do not degrade surge capability after multiple surge events within limit. P-3ACL fails short circuit when surged in excess of ratings. The RoHS Compliant components also offer low voltage overshoot and low on-state voltage.
