P1500TA 150V Thyristor Surge Suppressor SMA/DO-214AC | 800A Peak Surge | 150pF Capacitance | RUILON

The P1500TA Thyristor Surge Suppressor from RUILON is a high-performance transient protection device designed to protect sensitive electronic systems from high-energy surges and voltage spikes. Utilizing advanced thyristor (TSS) technology, this component provides ultra-fast switching response and efficient clamping performance, making it ideal for telecom, industrial, and power line protection applications.

With a breakover voltage range of approximately 140V to 180V, the P1500TA offers a higher voltage protection threshold compared to lower-rated devices, effectively reducing nuisance triggering while ensuring reliable surge suppression. Its high peak pulse current capability of up to 800A (8/20µs waveform) allows it to withstand severe surge conditions such as lightning strikes and switching transients.

The device features moderate capacitance of around 150pF, providing a good balance between signal integrity and surge handling capability, making it suitable for communication lines and power interfaces. Additionally, its low on-state voltage (~4–5V) ensures efficient conduction during surge events, minimizing power dissipation and improving overall system reliability.

Encased in a compact SMA (DO-214AC) surface-mount package, the P1500TA enables easy PCB integration and space-saving design flexibility. It is widely used in telecommunications equipment, industrial control systems, power supplies, and consumer electronics requiring dependable surge protection.
