The SMBJ90A TVS Diode from RUILON is a high-reliability 600W transient voltage suppressor designed to protect electronic circuits from voltage spikes, lightning surges, and electrostatic discharge (ESD). Utilizing advanced avalanche breakdown technology, this diode delivers ultra-fast response time and precise clamping performance, ensuring effective suppression of transient overvoltage events.
With a working peak reverse voltage of 90V, the SMBJ90A is ideal for higher-voltage applications requiring stable and efficient surge protection. It features a peak pulse power dissipation of 600W (10/1000µs waveform), enabling it to absorb and dissipate high-energy transients while maintaining circuit integrity. The device also offers low leakage current and optimized clamping characteristics, contributing to improved system efficiency and long-term reliability.
Compared to lower voltage TVS diodes, the 90V configuration provides greater voltage headroom, reducing the risk of unintended conduction in circuits with voltage fluctuations while maintaining strong surge suppression capability. Its compact SMB (DO-214AA) surface-mount package supports space-saving PCB layouts and seamless integration into modern electronic designs.
The RUILON SMBJ90A is widely used in power supplies, automotive electronics, telecom systems, industrial control equipment, and consumer electronics, delivering dependable protection, extended service life, and consistent performance in demanding environments.
