PA150T 150V Thyristor Surge Suppressor SMA/DO-214AC | 80A Surge Current Protection | Low Capacitance | RUILON

The PA150T Thyristor Surge Suppressor from RUILON is a high-reliability transient voltage protection device designed to safeguard sensitive electronic circuits from electrostatic discharge (ESD), lightning surges, and switching transients. Utilizing advanced thyristor-based (TSS) technology, it provides ultra-fast response and precise clamping performance, making it ideal for protecting low-voltage communication and signal interfaces.

With a breakover voltage range of approximately 120V to 142V, the PA150T ensures accurate and stable protection behavior, reducing false triggering while maintaining strong surge suppression capability. Compared to higher-voltage variants, this device is optimized for lower-voltage systems where fast and precise response is critical.

The PA150T supports a surge current capability of up to 80A (8/20µs waveform), ensuring reliable protection against transient overvoltage events such as lightning-induced surges and switching noise. Its low capacitance design helps preserve signal integrity, making it highly suitable for high-speed data and communication lines. Additionally, its low on-state voltage reduces power loss and improves thermal efficiency during surge events.

Packaged in a compact SMA (DO-214AC) surface-mount form factor, the PA150T offers excellent PCB integration, space savings, and strong mechanical reliability. It is widely used in telecom systems, industrial electronics, consumer devices, and interface protection applications requiring precise and fast transient suppression.
