Baseband Voice DS1 SIDACtor Protection Thyristors

Littelfuse Baseband Voice DS1 SIDACtor® Protection Thyristors focus on addressing the performance and regulatory requirements of baseband telecommunications equipment such as voice, modems, and DS1. SIDACtor components are solid-state crowbar devices that protect telecom equipment during hazardous transient conditions. Utilizing a patented ion implant technology, effective protection is ensured within nanoseconds. Littelfuse Baseband Voice DS1 SIDACtor Protection Thyristors offer an overvoltage protection solution that helps applications comply with Telcordia GR-1089 Issue 4, ITU-T recommendations K.20, K.21, K.44, and K.45, and TIA-968-A.
