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.
