The Littelfuse Inc. SG150 is a Gas Discharge Tube (GDT) from the SJ Series, designed for high surge ratings in a miniature package. It features a 2-pole configuration and is suitable for surface mounting on PCBs, with dimensions of 1812 (4532 Metric).
This GDT operates at 150V and has a nominal impulse discharge current of 3kA (8/20μS pulse), with a maximum surge capability of 5kA. It offers low insertion loss, making it ideal for broadband equipment applications. The device exhibits very low capacitance, less than 0.5pF, ensuring minimal signal loss at high frequencies.
Key electrical characteristics include a DC breakdown voltage range of 120V to 180V and an impulse breakdown voltage of 500V to 600V. The on-state voltage is typically 9V at 1 Amp. It is constructed with a ceramic insulator and tin-plated materials.
Applications for the SG150 include communication equipment, CATV, test equipment, data lines, power supplies, and telecom SLIC protection. It is RoHS compliant and lead-free, with a storage and operational temperature range of -40°C to +125°C.
