Gas discharge tube protects against fast-rising transients
Measuring 5.0 x 5.0 x 4.2mm, the SH series gas discharge tube (GDT) is the smallest available with a 5kA surge capability and 0.7pF off-state capacitance values to minimise insertion losses, says Littelfuse.
The SH series GDT is designed to provide high levels of protection against fast-rising transients caused by lightning disturbances. Its low off-state capacitance is compatible with high bandwidth applications, says the company, and this capacitance loading value does not vary if the signal voltage across the GDT changes. It was specifically designed for protection of electrical, multimedia, and communication equipment against over-voltage transients.
Typical applications include G.fast, xDSL, 10GbE, and 10/100/1000 Base-T Ethernet port protection for telecoms and datacomms, coaxial cable protection in satellite, CATV equipment and set-top boxes for consumer products; industrial automation interfaces such as Ethernet, RS-485, RS-232, for the industrial market; and AC power line protection in power inverter or variable frequency drives (VFDs) for the renewable energy market.
SH series Gas Discharge Tubes are available in tape and reel packaging
