Built with advanced ceramic gas discharge technology, this device ensures fast and reliable response to lightning strikes, switching surges, and other high-energy disturbances.\u003c\/p\u003e\n\u003cp data-start=\"505\" data-end=\"1004\"\u003eWith a DC spark-over voltage of 4000V, the 2R4000T-8T is ideal for applications that demand higher voltage thresholds compared to lower-rated GDT series. This higher breakdown voltage minimizes the risk of unintended triggering while delivering superior surge handling performance, making it suitable for harsh electrical environments. Its high insulation resistance and low capacitance at 1 MHz enable effective protection of both power and high-speed signal lines without compromising performance.\u003c\/p\u003e\n\u003cp data-start=\"1006\" data-end=\"1358\"\u003eThe device offers stable glow voltage and arc voltage characteristics, ensuring efficient transition and energy dissipation during surge events. It supports high impulse discharge current capability (8\/20µs waveform) and excellent impulse withstanding voltage, contributing to long service life and consistent reliability under repeated surge exposure.\u003c\/p\u003e\n\u003cp data-start=\"1360\" data-end=\"1642\"\u003eEncapsulated in the durable 2R-8T ceramic package, the 2R4000T-8T allows easy integration into various circuit designs. It is widely used in telecommunications, power systems, industrial electronics, and surge protection modules where dependable high-voltage protection is critical.\u003c\/p\u003e\n\u003chr
