P3500TA 350V Thyristor Surge Suppressor SMA/DO-214AC | 800A Peak Surge | 150pF Capacitance | RUILON

RUILON

The P3500TA Thyristor Surge Suppressor from RUILON is a high-performance transient protection device designed to protect sensitive electronic circuits from high-energy surges and voltage spikes. Built with advanced thyristor (TSS) technology, this component delivers ultra-fast switching response and strong clamping capability, making it ideal for telecom, industrial, and power line protection applications.

With a breakover voltage range of approximately 320V to 400V, the P3500TA provides a higher voltage protection threshold compared to lower-rated devices, effectively reducing nuisance triggering while ensuring reliable suppression of transient overvoltages. Its high peak pulse current capability of up to 800A (8/20µs waveform) allows it to handle severe surge conditions such as lightning strikes and switching transients.

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 events, reducing thermal stress and improving overall system reliability.

Encased in a compact SMA (DO-214AC) surface-mount package, the P3500TA enables easy PCB integration and space-saving design flexibility. It is widely used in telecommunications equipment, industrial automation systems, power supplies, and consumer electronics requiring dependable surge protection.
