The SG350Q is a 2-electrode gas discharge tube (GDT) manufactured by Littelfuse Inc. It provides overvoltage protection with a DC breakdown voltage of 350V and an impulse discharge current rating of 1000A (1kA) for an 8/20µs waveform. The device is designed for surface mount assembly and comes in a compact 1812 (4532 Metric) package.
The SG350Q does not feature a fail-short mode, meaning it does not short circuit upon end of life. It is part of the SJ series of GDTs, which are known for high surge capability in a miniature form factor. The component is suitable for use in communication equipment, data lines, and broadband applications where low capacitance and fast response to transients are required.
The part is RoHS3 compliant and has an MSL rating of 1 (unlimited). It is also REACH unaffected. The package is a standard 1812 surface mount case, making it compatible with automated assembly processes.
