The 5KP400A TVS Diode from RUILON is a high-reliability 5000W transient voltage suppressor engineered to protect sensitive electronic circuits from voltage surges, lightning transients, switching spikes, and electrostatic discharge (ESD). Built with advanced silicon avalanche technology, it delivers ultra-fast response time and exceptional surge energy absorption capability, ensuring stable and dependable protection in harsh electrical environments.
With a 400V reverse standoff voltage, the 5KP400A is specifically designed for high-voltage DC and industrial power systems, offering a wide operating margin and strong overvoltage clamping performance. Its high peak pulse power rating of 5000W (10/1000µs waveform) enables it to efficiently absorb large transient energy, significantly reducing stress on downstream components and improving overall system reliability.
The rugged P600 axial package ensures excellent thermal dissipation and mechanical durability, making it ideal for through-hole PCB mounting in industrial, telecom, and power electronics applications. Compared with lower-voltage TVS diode series, the 5KP400A provides superior surge endurance and enhanced protection capability for high-voltage environments.
Engineered for long-term stability, this device features low clamping voltage, fast response characteristics, and high junction robustness, making it a dependable solution for modern surge protection requirements.
