Utilizing advanced ceramic gas discharge technology, this DIP series device delivers rapid response to transient events such as lightning surges, switching spikes, and electrical disturbances.\u003c\/p\u003e\n\u003cp data-start=\"540\" data-end=\"933\"\u003eWith a nominal static breakdown voltage of approximately 400V, the 2R400TK-5 provides a higher protection threshold compared to lower voltage GDTs, effectively reducing the risk of nuisance triggering while maintaining strong surge suppression capability. Its ultra-fast breakdown time of less than 50 ns ensures immediate activation, protecting sensitive circuits from high-energy transients.\u003c\/p\u003e\n\u003cp data-start=\"935\" data-end=\"1363\"\u003eThe device demonstrates stable ignition characteristics, including reliable first ignition performance after extended periods of inactivity and consistent following ignition values during continuous operation. It supports high peak discharge current capability of up to ~500A, ensuring excellent surge handling performance. Its robust electrical life and high switching durability make it suitable for repeated surge conditions.\u003c\/p\u003e\n\u003cp data-start=\"1365\" data-end=\"1629\"\u003eEncased in a durable DIP package, the 2R400TK-5 enables easy through-hole mounting and strong mechanical stability.
