General
AOLITTEL'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.
Applications
■ Repeaters, Modems.
■ Telephone Interface, Line cards.
■ Data communication equipment.
■ Line test equipment

Gas Discharge Tubes - SE3 Series
SE33 - 230X F
SE3 Series: SE3:ф6*8 SE8:ф8*10
3 : Lead Type: 0=SMD 3=Thrust
230X : DC Line Voltage: 90X=90V 230X=230V 102X=1000V
F: Package F=With Fail-Short mechanism
BENEFITS
• Helps provide overvoltage fault protection against damage caused by high energy surges
• Suitable for use in sensitive equipment due to impulse sparkover response
• Suitable for high-frequency applications
• Highly reliable performance
• New surface-mount devices for automated manufacturing
Installation for Gas Discharge Tubes
Care should be taken when installing GDTs equipped with fail-short mechanisms into arrester magazines, printed circuit boards, etc. Too much downward pressure may force the short circuit spring through the thin insulation tube creating a shorted condition.
Solder Reflow Recommendations for Surface-mount GDT Devices
Surface-mount GDTs can be soldered using standard Pb-free reflow profiles.
