The SMCJ350A TVS Diode from RUILON is a high-performance 1500W transient voltage suppressor designed to protect sensitive electronic circuits from voltage spikes, lightning surges, and electrostatic discharge (ESD). Built with advanced avalanche breakdown technology, it delivers ultra-fast response time and precise clamping performance, ensuring reliable suppression of transient overvoltage events in industrial and electronic systems.
With a working peak reverse voltage of 350V, the SMCJ350A is ideal for protecting DC power lines, communication interfaces, industrial control systems, USB ports, and embedded electronic circuits. Its 1500W peak pulse power dissipation (10/1000µs waveform) provides strong surge absorption capability for high-voltage applications, ensuring robust protection in harsh electrical environments.
The device features ultra-low leakage current, stable clamping characteristics, and excellent thermal performance, ensuring consistent operation even under repeated surge stress. Compared to lower voltage variants, the 350V rating provides a high-level protection solution for higher medium-voltage and industrial systems while maintaining strong immunity against ESD and transient voltage spikes.
Encased in a compact SMC (DO-214AB) surface-mount package, the SMCJ350A supports high power handling in a space-efficient footprint, making it suitable for modern high-density PCB designs. It is widely used in industrial automation, power systems, communication equipment, and electronic devices requiring reliable surge protection.
