The PA180T Thyristor Surge Suppressor from RUILON is a high-performance transient voltage protection device designed to safeguard sensitive electronic circuits from ESD, lightning surges, and switching transients. Built on advanced thyristor (TSS) technology, it provides ultra-fast response time and precise clamping behavior, making it ideal for protecting communication interfaces and low-to-medium voltage electronic systems.
With a breakover voltage range of approximately 150V to 170V, the PA180T ensures accurate and stable triggering performance, effectively balancing protection sensitivity and operational stability. Compared to lower-voltage variants, it offers improved noise immunity while still delivering fast surge response.
The PA180T supports a surge current capability of up to 80A (8/20µs waveform), enabling reliable protection against high-energy transient events such as lightning-induced surges and inductive switching spikes. Its low capacitance design helps maintain signal integrity, making it highly suitable for high-speed data lines, communication ports, and sensitive signal applications. Additionally, its low on-state voltage improves energy efficiency and reduces thermal stress during surge conduction.
Housed in a compact SMA (DO-214AC) surface-mount package, the PA180T offers excellent PCB integration, mechanical reliability, and space-saving advantages. It is widely used in telecom equipment, industrial systems, consumer electronics, and interface protection modules requiring dependable transient suppression.
