BOURNS 2420 overvoltage protector has low cost, fast response, high energy handling and low capacitance.
The Bourns 2420 Series is a 5-pin Gas Discharge Tube (GDT) protector designed for overvoltage protection in broadband voice and data circuits, including ADSL, VDSL, and Ethernet. It utilizes a proprietary high-efficiency gas discharge tube with a patented Switch-Grade Fail-Short mechanism to provide robust surge and thermal overload protection. The design eliminates the air back-up gap found in common chambers, preventing contamination and ensuring reliability.
