The 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.
