The SMBJ85A TVS Diode from RUILON is a high-performance 600W transient voltage suppressor designed to protect sensitive electronic circuits from voltage spikes, lightning surges, and electrostatic discharge (ESD). Built with advanced avalanche breakdown technology, this diode ensures ultra-fast response time and precise clamping capability, delivering reliable protection against transient overvoltage events.
With a working peak reverse voltage of 85V, the SMBJ85A is ideal for higher-voltage applications that require stable and efficient surge suppression. It features a peak pulse power dissipation of 600W (10/1000µs waveform), allowing it to absorb and dissipate significant surge energy while maintaining circuit integrity. The device also offers low leakage current and optimized clamping characteristics, enhancing overall system efficiency and long-term reliability.
Compared to lower voltage TVS diodes, the 85V configuration provides increased voltage headroom, reducing the risk of unintended conduction in circuits with voltage fluctuations while maintaining strong protection capability. Encased in a compact SMB (DO-214AA) surface-mount package, it supports space-efficient PCB layouts and easy integration into modern electronic systems.
The RUILON SMBJ85A is widely used in power supplies, automotive electronics, telecom equipment, industrial control systems, and consumer devices, ensuring dependable protection, extended service life, and consistent performance in demanding environments.
