The Littelfuse SG500Q is a gas discharge tube (GDT) designed for overvoltage protection in electronic circuits. It offers a DC breakdown voltage of 500V and can handle impulse discharge currents up to 1000A (1kA) with an 8/20μs waveform. The device features 2 poles and is configured for surface-mount assembly.
This GDT is housed in an industry-standard 1812 (4532 Metric) package, making it suitable for compact PCB layouts. It is RoHS compliant and lead-free as stated in the datasheet. The SG500Q belongs to the SJ series, which is recognized for high surge ratings and low capacitance, suitable for broadband and telecom applications.
The part does not fail short. Designers should note that the MSL and REACH status are unverified and require confirmation from official sources.
