P1800TA 180V Thyristor Surge Suppressor SMA/DO-214AC | 800A Peak Surge | 150pF Capacitance | RUILON

The P1800TA Thyristor Surge Suppressor from RUILON is a high-performance transient voltage protection device engineered to safeguard sensitive electronic circuits from high-energy surges and voltage spikes. Utilizing advanced thyristor (TSS) technology, this component delivers ultra-fast switching response and robust clamping capability, making it ideal for telecom, industrial, and power line protection applications.

With a breakover voltage range of approximately 170V to 220V, the P1800TA provides a higher protection threshold compared to lower voltage devices, effectively minimizing nuisance triggering while ensuring reliable surge suppression. Its high peak pulse current capability of up to 800A (8/20µs waveform) ensures strong protection against lightning strikes, switching transients, and other surge events.

The device features moderate capacitance of around 150pF, offering a balanced combination of signal integrity and surge robustness, making it suitable for communication interfaces and power lines. Additionally, its low on-state voltage (~4–5V) ensures efficient conduction during surge conditions, reducing thermal stress and enhancing overall system reliability.

Encased in a compact SMA (DO-214AC) surface-mount package, the P1800TA provides excellent PCB integration and space-saving advantages. It is widely used in telecommunications equipment, industrial automation systems, power supplies, and consumer electronics requiring dependable surge protection.
