Description

SIDACtor components are solid state crowbar devices designed to protect telecom equipment during hazardous transient conditions. Capitalizing on the latest in thyristor advancements, Teccor makes SIDACtor devices with a patented ion implant technology. This technology ensures effective protection within nanoseconds, up to 5000 A surge current ratings, and simple solutions for regulatory requirements such as GR 1089, TIA-968 (formerly known as FCC Part 68), ITU-T K.20, ITU-T K.21, and UL 60950.

Specifications and features

SIDACtor devices offer absolute surge protection regardless of the surge current available and the rate of applied voltage (dv/dt). They cannot be damaged by voltage and eliminate hysteresis and heat dissipation typically found with clamping devices. SIDACtor devices also eliminate voltage overshoot caused by fast-rising transients, are non-degenerative, will not fatigue, and have low capacitance, making them ideal for high-speed transmission equipment.

Application Scenarios

SIDACtor devices are commonly used in various telecommunication circuits for protection. They are connected across Tip and Ring for metallic protection and across Tip and Ground and Ring and Ground for longitudinal protection. They are typically placed behind a current-limiting device like Teccor’s F1250T Telelink slow blow fuse. Common applications include central office line cards (SLICs), T-1/E-1, ISDN, and xDSL transmission equipment, customer premises equipment (CPE) such as phones, modems, and caller ID adjunct boxes, PBXs, KSUs, and other switches, primary protection including main distribution frames, five-pin modules, building entrance equipment, and station protection modules, data lines and security systems, CATV line amplifiers and power inserters, and sprinkler systems.
