The SMBJ190A TVS Diode from RUILON is a high-performance 600W transient voltage suppressor engineered to protect sensitive electronic circuits from voltage spikes, lightning surges, and electrostatic discharge (ESD). Designed with advanced avalanche breakdown technology, this diode ensures ultra-fast response time and precise clamping performance, effectively suppressing transient overvoltage conditions.
With a working peak reverse voltage of 190V, the SMBJ190A is ideal for high-voltage applications requiring stable and reliable surge protection. It features a peak pulse power dissipation of 600W (10/1000µs waveform), enabling it to absorb and dissipate substantial transient energy while maintaining circuit integrity. The device also offers low leakage current and optimized clamping characteristics, enhancing system efficiency and long-term reliability.
Compared to lower voltage TVS diodes, the 190V configuration provides increased voltage headroom, minimizing the risk of unintended conduction in circuits with voltage fluctuations while maintaining strong surge suppression 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 SMBJ190A is widely used in power supplies, industrial control systems, telecom equipment, automotive electronics, and consumer devices, delivering dependable protection, extended service life, and consistent performance in demanding environments.
