The Bourns

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

VDSL2 and high-speed Ethernet. The 2420 Series is an economical, reliable and low capacitance choice for overvoltage protection

of copper pair circuits.
