without notice. the device characteristics and parameters in this data sheet can and do vary in different applications and actual device perfor mance may vary over time. users should verify actual device performance in their speci? c applications. the bourns ? 3-type model 2420 overvoltage protection modules utilize bourns proprietary high-ef? ciency 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 listed for use without a back-up device. air back-up devices can become contaminated; the circuitry of the 2420 eliminates the air back-up gap and thus the poss ibility of its contamination. our unique switch-grade fail-short device provides more reliable thermal overload protection compared to co m- monly used solder pellet or insulation burn-through designs. bourns ? model 2420 series 5-pin protectors can be used universally for broadband voice and data circuits including adsl, adsl2+, vdsl, vdsl2 and high-speed ethernet. the 2420 series is an economical, reliable and low capacitance choice for overvoltage protection of copper pair circuits. test methods per
