The Bourns® 3-Type 2420 Overvoltage Protection Modules Utilize Bourns’ Propietary High-Efficiency Gas Discharge Tube With Our Patented Switch-Grade Fail-Short Mechanism To Provide Robust And Reliable Surge And Thermal Overload Protection At A Very
Competitive Price. The 2420 Series Is Based On Bourns’ Three-Terminal Common Chamber Gdt. This Design Provides Greatly Improved And Balanced Turn-On Characteristics For Overvoltage Protection.The Gdt Is Ul Approved For Use Without A Back-Up
Device. Air Back-Up Devices Can Become Contaminated; The Circuitry Of The 2420 Eliminates This Possibility. Our Unique Switch-Grade Fail-Short Device Provides More Reliable Thermal Overload Protection Compared To Commonly Used Solder Pellet Or
Insulation Burn-Through Designs. Bourns® 2420 Series 5-Pin Protectors Can Be Used Universally For Broadband Voice And Data Circuits Including Adsl, Adsl2+, Vdsl Isdn And High-Speed Ethernet. The 2420 Series Is An Economical, Reliable And Low Capacitance Choice For Overvoltage Protection Of Copper Pair Circuits.
