The Littelfuse SG300Q is a gas discharge tube (GDT) designed for overvoltage protection in a compact surface mount package. It features a nominal DC breakdown voltage of 300V and an impulse discharge current rating of 1kA (8/20μs waveform), making it suitable for secondary surge protection in telecom and data line applications.
The component has 2 poles and a fail-short mode of No, indicating it is designed to fail open under extreme conditions. It is housed in an industry-standard 1812 (4532 Metric) ceramic package that supports surface mount assembly, saving board space.
Listed as RoHS3 compliant with MSL 1 (unlimited floor life) and REACH unaffected, though these compliance statements are unverified. The part is associated with the SJ series of GDTs, which are recognized for high surge capability in miniature form factors.
