The 2RL300L-5 GDT/TSS manufactured by Yageo is a RoHS-compliant discharge tube that is designed to provide protection against transient electrical conditions. This device is used to protect electrical circuits from high-voltage surges, such as lightning strikes. It is composed of two general-purpose, low-inductance GDTs (Gas Discharge Tubes) and two TSS (Transient Suppressor Stacks). The device features a high surge current tolerance of up to 20kA (8/20µs) and a low let-through voltage of just 4V (8/20µs). It can be installed directly onto a printed circuit board and has an operating and storage temperature range of -40°C to +85°C. The tube also features a surge clamping voltage of 300V and is designed to meet UL1449 and IEC61964 standards.
