GAS DISCHARGE TUBES (GDTS) Littelfuse's GDTs (Gas Discharge Tubes) are placed in front of, and in parallel with, sensitive telecom equipment such as power lines, communication lines, signal lines and data transmission lines to help protect them from damage caused by transient surge voltages that may result from lightning strikes and equipment switching operations. These devices do not influence the signal in normal operation. However, in the event of an overvoltage surge, such as a lightning strike, the GDT switches to a low impedance state and diverts the energy away from the sensitive equipment. Our GDTs offer a high level of surge protection, a broad voltage range, low capacitance, and many form factors including new surface mount devices, which makes them suitable for applications such as Main Distribution Frame (MDF) modules, high data-rate telecom applications (e.g. ADSL, VDSL), and surge protection on power lines. Their low capacitance also results in less signal distortion. When used in a coordinated circuit protection solution with PolySwitch devices, they can help equipment manufacturers meet stringent safety regulatory standards.

Under normal operating conditions, the pellet is positioned to make the spring float above the outer electrodes, as shown in Figure G11 on the previous page.. Outer Electrode Ceramic Tube When a prolonged discharge event causes the gas tube temperature to reach the melting point of the solder, the pellet softens allowing the short circuit spring to contact with both outer electrodes (Figure G12). This process results in a permanent short circuit bet ween all three electrodes creating a low resistance path that conducts the fault current to ground Center Electrode without generating a significant amount of heat. Fail-Short Mechanism — FT Figure G13 Short Circuit Spring Plastic Foil The FT fail-short mechanism is a short circuit spring with a piece of plastic foil spot welded onto the center electrode. Under normal operating conditions, the plastic foil makes the spring insulated from the two outer electrodes. When a prolonged discharge event causes the gas tube temperature to reach the melting Outer Electrode Ceramic Tube point of the plastic foil, the plastic foil melts allowing the short circuit spring to contact both outer electrodes (Figure G13). This process results in a permanent short circuit bet ween all three electrodes creating a low resistance path that conducts the fault current to ground Center Electrode without generating a significant amount of heat.

Solder Reflow Recommendations for Surface-mount GDT Devices Surface-mount GDTs can be soldered using standard Pb-free reflow profiles.
