PA220T 220V Thyristor Surge Suppressor SMA/DO-214AC | 80A Surge Protection Device | Low Capacitance | RUILON

The PA220T Thyristor Surge Suppressor from RUILON is a high-performance transient voltage protection device designed to protect sensitive electronic circuits from electrostatic discharge (ESD), lightning surges, and switching transients. Built on advanced thyristor (TSS) technology, it delivers ultra-fast response time and precise clamping performance, making it ideal for telecom, industrial, and communication interface protection.

With a breakover voltage range of approximately 190V to 210V, the PA220T provides a stable and well-controlled triggering threshold, ensuring effective surge suppression while minimizing false triggering during normal operating conditions. This makes it well-suited for mid-voltage protection applications that require both accuracy and reliability.

The PA220T supports a surge current capability of up to 80A (8/20µs waveform), providing strong resilience against high-energy transient events such as lightning-induced surges and inductive switching spikes. Its low capacitance design helps maintain excellent signal integrity, making it highly suitable for high-speed data lines, communication ports, and sensitive signal circuits. Additionally, its low on-state voltage improves efficiency and reduces thermal stress during surge conduction.

Encased in a compact SMA (DO-214AC) surface-mount package, the PA220T ensures easy PCB integration, excellent mechanical stability, and space-saving design flexibility. It is widely used in telecommunications systems, industrial automation, consumer electronics, and interface protection modules requiring reliable transient suppression.
