2420 Series - 5-Pin Gas Discharge Tube (GDT) Protector
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 possibility of
its contamination. Our unique Switch-Grade Fail-Short device provides more reliable thermal overload protection compared to com-
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.
