SMCJ250A 250V 1500W TVS Diode SMC/DO-214AB | High Power Transient Voltage Suppressor for Surge & ESD Protection | RUILON

RUILON

The SMCJ250A 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 250V, the SMCJ250A 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 significantly higher surge absorption capability compared to standard 600W and 1000W TVS diodes, ensuring strong protection in demanding 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 250V rating provides a robust protection level for higher medium-voltage systems while maintaining strong immunity against ESD and transient voltage spikes.

Encased in a compact SMC (DO-214AB) surface-mount package, the SMCJ250A supports high power handling in a space-efficient footprint, making it suitable for modern high-density PCB designs. It is widely used in consumer electronics, communication systems, industrial automation, and embedded applications requiring reliable surge protection.
