1.0SMBJ28A 28V 1000W TVS Diode SMB/DO-214AA | High Power Transient Voltage Suppressor for Surge & ESD Protection | RUILON

The 1.0SMBJ28A 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). Utilizing advanced avalanche breakdown technology, this device delivers ultra-fast response time and precise clamping performance, ensuring effective suppression of transient overvoltage events.

With a working peak reverse voltage of 28V, the 1.0SMBJ28A is well-suited for low-voltage to mid-voltage applications such as DC power rails, communication interfaces, and embedded electronic systems. Its high peak pulse power dissipation of 1000W (10/1000µs waveform) provides significantly improved surge absorption capability compared to standard 600W TVS diodes, enhancing system robustness and long-term reliability.

The device features low leakage current, stable clamping characteristics, and excellent thermal performance, ensuring efficient operation under demanding electrical conditions. Compared to lower voltage variants, the 28V configuration offers increased voltage headroom, reducing the risk of unintended triggering while maintaining strong transient suppression capability.

Encased in a compact SMB (DO-214AA) surface-mount package, the 1.0SMBJ28A supports space-efficient PCB design and easy integration into modern electronic systems. It is widely used in consumer electronics, power supplies, communication equipment, and industrial control systems, delivering dependable protection and consistent performance.
