The 1.0SMBJ85A TVS Diode from RUILON is a high-performance 1000W 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 demanding industrial and electronic environments.
With a working peak reverse voltage of 85V, the 1.0SMBJ85A is suitable for mid-voltage applications such as DC power distribution, industrial automation systems, communication equipment, and embedded electronics. Its 1000W peak pulse power dissipation (10/1000µs waveform) provides significantly higher surge absorption capability compared to standard 600W TVS diodes, enhancing overall system protection and reliability.
The device features low leakage current, stable clamping characteristics, and excellent thermal performance, ensuring efficient operation even under repeated surge conditions. Compared to lower voltage variants, the 85V rating offers increased voltage headroom, reducing the risk of false triggering while maintaining strong transient suppression capability.
Encased in a compact SMB (DO-214AA) surface-mount package, the 1.0SMBJ85A supports space-efficient PCB layouts and easy integration into modern electronic designs. It is widely used in consumer electronics, power supplies, telecom systems, industrial control systems, and embedded applications requiring robust surge protection.
