The SMA6J75A from RUILON is a high-performance 400W Transient Voltage Suppressor (TVS) diode designed 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 stability and efficient PCB space utilization, making it ideal for modern high-density electronic designs.
With a 75V reverse standoff voltage, the SMA6J75A is optimized for higher-voltage power rails and signal line protection, ensuring stable circuit 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 features a peak pulse power dissipation of 400W (10/1000 µs waveform), providing strong energy absorption capability and reliable performance under repeated surge events. Compared to lower-voltage TVS diodes, the SMA6J75A offers a higher breakdown threshold, making it suitable for applications requiring improved voltage margin and enhanced system robustness.
Built using advanced silicon avalanche technology, it ensures low leakage current, precise clamping performance, and long-term operational reliability. This makes it a dependable solution for protecting electronic systems operating in harsh electrical environments with frequent transient disturbances.
