The SMA6J64A from RUILON is a high-reliability 400W Transient Voltage Suppressor (TVS) diode engineered to protect sensitive electronic circuits from voltage transients, electrostatic discharge (ESD), and surge-induced stress. Packaged in a compact SMA (DO-214AC) surface-mount form factor, it delivers strong surge-handling capability while maintaining excellent thermal performance and efficient PCB space utilization, making it ideal for modern high-density electronic designs.
With a 64V reverse standoff voltage, the SMA6J64A is optimized for medium-voltage power rails and signal line protection, ensuring stable operation under normal conditions while rapidly clamping harmful transient voltage spikes. Its ultra-fast response time enables immediate suppression of surge energy, effectively safeguarding critical components such as ICs, microcontrollers, and communication interfaces.
The device supports a peak pulse power dissipation of 400W (10/1000 µs waveform), providing robust energy absorption and reliable performance under repeated surge conditions. Compared to lower-voltage TVS diodes, the SMA6J64A offers a higher breakdown threshold, making it suitable for applications requiring increased voltage margin and improved system-level robustness.
Built using advanced silicon avalanche technology, it ensures low leakage current, precise clamping behavior, and long-term operational stability. This makes it a dependable solution for protecting electronic systems operating in harsh electrical environments with frequent transient disturbances.
