2R350TK-5 350V DIP Gas Discharge Tube | Fast Response GDT <50ns | High Surge Current ~500A | RUILON

The 2R350TK-5 Gas Discharge Tube (GDT) from RUILON is a high-reliability surge protection component engineered for medium-voltage applications requiring robust and stable overvoltage protection. Utilizing advanced ceramic gas discharge technology, this DIP series device provides rapid response to lightning surges, switching transients, and other high-energy electrical disturbances.

With a nominal static breakdown voltage of approximately 350V, the 2R350TK-5 offers an optimal balance between protection sensitivity and system stability. Compared to lower voltage GDTs, it reduces the likelihood of nuisance triggering while maintaining effective surge suppression. Its ultra-fast breakdown time of less than 50 ns ensures immediate activation, protecting sensitive circuits from damage.

The device demonstrates stable first ignition characteristics after prolonged inactivity and consistent following ignition values during continuous operation. It supports high peak discharge current capability of up to ~500A, ensuring strong surge handling performance. Additionally, its excellent electrical life and switching durability enable reliable operation under repeated surge events.

Housed in a durable DIP package, the 2R350TK-5 allows easy through-hole installation and strong mechanical stability. It is widely used in telecom systems, power supplies, industrial controls, and surge protection modules where dependable protection is essential.
